Title: Ardutester - Arduino Component Tester
Post by: pighixxx on May 02, 2013, 03:16 pm
22/0/2013 UPDATE!
New Version 0.7x
Attention! The connection diagram has changed!

ArduTester

This is an Arduino porting of the excellent work by Markus Frejek.
The final aim is to create an economic component tester using Arduino and a few passive components;
I'm trying to make the system more scalable as possible, so you can view the output in Serial Terminal or alternatively via a I2C LCD.
I'm working on a shield which will also include the components for the Logic Analyzer (Another project of ABC). For my convenience i publish first SMD version  and then TH Version.

Logically all the updated files will be available at this first post.  :D

This is the basic design:

Files download:

Schematic (http://at.pighixxx.com/disp35e.pdf)
Sketch v0.7f (27/07/2013) (http://at.pighixxx.com/ardutester.ino)

In the coming days will be available the new gerber files and the new shield layout.

This is a preview. Testing a 100nf capacitor.

ArduTester features:
- Automatic detection of NPN and PNP bipolar transistors, N- and P-Channel MOSFETs, JFETs, diodes, double diodes, Thyristors, Triacs, resistors and capacitors.
- Automatic detection of pin layout of the detected part.
- Measuring of current amplification factor and Base-Emitter threshold voltage of bipolar transistors.
- Detection of the protection diode of bipolar transistors and MOSFETs
- Measuring of the Gate threshold voltage and Gate capacity value of MOSFETs.

and much more!

Looks very good!, thanks for sharing!

( should this not be in the science or exhibition section? )

When do you think to have kits available?  - It would be nice if the kit includes all even an ABC box

First of all I would like to say thank you very much! for all your hard work Pighixxx with the Arduino ABC and this project 8)

I have built the current Circuit on breadboard this morning ,Could you explain a little about using the probes for various components, plus a few other things such as Such as "GDS" ETC

Which parts of the code do I need to change for a 20x4 display ? other than  "LiquidCrystal_I2C lcd(LCD_ADDRESS,16,2);"
I find the constant cycling of the readings on a 16x2 display some what confusing at the moment .

I was also wondering what pin does "#define BUTTON_INST" use ? Does it go to GND?

Thanks again for all you hard work

Best regards

Rupert

You can use any pin for the tested component. Ardutester will give you the pinout.
Have You tested a fet? GDS mean Gate, Drain, Source (the pins of a Fet)  8)


Which parts of the code do I need to change for a 20x4 display ? other than  "LiquidCrystal_I2C lcd(LCD_ADDRESS,16,2);"
I find the constant cycling of the readings on a 16x2 display some what confusing at the moment .


Waiting for the next release (07x), I'll add the code for custom lcd (20x4, etc)


I was also wondering what pin does "#define BUTTON_INST" use ? Does it go to GND?


If You have a button installed (see schematic on first post - pin 2 to gnd)


Thanks again for all you hard work

Title: Re: Ardutester - Arduino Component Tester
Post by: koogar on May 05, 2013, 06:18 pm
Just as a note I am using LiquidCrystal_I2C V2.0, and the back light is connected from PCF8574 "P7"  as per Pighixxx ABC Guide but with a 3904 transitor.

the back light was doing the opposite of the Code. I assume the backlight timeout is to save the battery if used.

At first i thought the NPN transistor was connected in reverse or i was using a PNP

As I am no good at code I had to perform a workaround and to edit the LiquidCrystal_I2C.h

From

// flags for backlight control
#define LCD_BACKLIGHT 0x00
#define LCD_NOBACKLIGHT 0x80

to

// flags for backlight control
#define LCD_BACKLIGHT 0x80
#define LCD_NOBACKLIGHT 0x00

Now the Backlight works as intended in the code.

Update: in the end I decided to use a PNP 3906 transistor an leave the code

Thanks

Rupert

Great work

I notice that on breadboard the capacitance tests are not that great, and even with no cap in place you still get significant reading.I realize this probably to do with the capacitance of leads/connections.

A relative function would be great to "REL" the leads rather than trimming in the code.

I was also thinking that a ESR reading of the cap may also be a useful measurement to display.

Cheers

You can increase de value of #define CAP_PROBELEADS & #define CAP_WIRES  :D

Hi Rupert,

the code is in constant development and in a few days will be released an improved version.
I'm working on inductance meter and ESR meter; all in ArduTester!

with 07 version will be introduced a new function: PC link.
I'm writing a cross-platform software that once you connected to Ardutest provide additional information about tested components.  :D

I'm continuing the development of software that will interface with Ardutester.
I will not reveal all of the features it will have, will be a surprise.
A nice thing, which I think no one has ever implemented, it's the acquisition of data and access to a database of components.
I decided to extract a part (The transistor finder) and publish it:

(http://pgdev.pighixxx.com/sw/tf.png)

This is an alpha version, only makes the transistor search. The final version will provide a lots of information of the transistor.
A small summary:

- Pin and case
- All relevant information (Polarity, UCB, Uce, EPO, Ft, Ic, CCtip, Pc, Material, Tj, Hfe)
- equivalent
- Finding and equivalent transistor for Euro, Americans, Russians and Japanese transistors
- Parametric search for any value
- Use of the transistor
- And more

I have no small signal diode but made the test with the emitter-base jonction of a transistor
I have not that behavior with a duemilanove. But sometime the capacitance measurement returns a very high value 76µF for example. But as my assembly is made on a testboard and the contacts are not very reliable I can't make any assumption concerning the software. I really must do a good board for a usable tool.

Shield: mini-solderless breadboard

solderless breadboards have not reliable contact. You can not make any assumption on the software with such an assembly. The jumpers on the breadboard can make very poor contact and so voltage drop can be high.
I have a similar assembly and from time to time I have crazy results. I shake a connection and the result is good. I shake another connection and the arduino hangs.
To qualify the software and the hardware you need a good printed board. Even with a good board the probes (or test socket) should have reliable contacts to guaranty a good measure.
Title: Re: Ardutester - Arduino Component Tester
Post by: mrburnette on Aug 23, 2013, 10:39 pm
@fdufnews:

It is rare that I take exception to statements made in good intentions, but in this case, I must mention that every Arduino shield uses "spring loaded" contacts.  This and the knowledge that solderless breadboards, in general, may be prone to connection issues is why I made multiple test with my Fluke multimeter.  I also used more than one row for testing diodes. 

Still, your statements ring true, but cannot account why every transistor tested was correctly analyzed properly as NPN or PNP and the gain was within 20% of published in spec. Sheet.  Yet multiple diodes always presented strange results, using same contact positions as the transistors (or even with alternate contacts.)

I've been a hardware engineer for 41 years and I admit to making silly mistakes from time-to-time, but I'm betting on the strange behavior i observed being software related.

Hi,

Thank you for an AWESOME contribution to the community! As a beginner to electronics I find this incredibly useful.

The only measurements which I found to be VASTLY off were resistance (and capacitance for 1 particular capacitor). For resistors 100 to 100k it was fairly consistently reporting a 60% (approx.) lower value. For 10R it was closer, but still about 30% off, but for 1M it was spot on.

Also, I wanted to use my I2C LCD display so I changed the #ifdef LCD_PRINT from what i currently contains in the latest release to:

Code: [Select]

#include <Wire.h>
#include <LiquidCrystal_I2C.h>
LiquidCrystal_I2C lcd(0x27, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE); // Addr, En, Rw, Rs, d4, d5, d6, d7, backlighpin, polarity


This works for me when used with the HelloWorld_i2c example, but does not seem to work with Ardutester. May I ask, why was support for I2C LCD's dropped?

Thanks in advance.

Regards,
Michal

P.S. I am using he NewLiquidCrystal library.

P.P.S I'm a little concerned about diode measurements too as my multimeter gave 500mV while Ardutester gave 200mV. I'll need to get more diodes to test as one diode is far from definitive.

Hi Alberto,

Thank you for your prompt response. I'm glad to hear a new version is coming soon :)

I tried changing the button to both A$ and A5 (with grounding A3 and without), but either way it gets stuck in the menu and I can't probe at all. I can keep trying to exit the menu but it goes right back in. I have no idea why it does this for A4 and A5 but not A3.

Any suggestions on what might be happening and how I might debug it?

Regards,
Michal

I tried A4 and A5.

The change does not work, as it appears to the S/W that the button is "always" pressed; that is, upon reset, the menu immediately starts to execute and eventually 'hangs'.

I extended A4 and A5 both with an external 10K to +5V (even though I noticed the code activates the weak internal pullup) but this did not change results.

Understand "very busy".  As time permits.  It is obvious that you spent much time on this project and I am sure many tested.  No problem with caps or transistors.  Resistors are 'off' but I do not see this function as important as correct diode detection.

Regards,

Ray

Are you sending the shield soon so I can try it?

Hi! I have a problm with ardutester. Built one on bread board but when there is nothing connected,  device shows me capacitor in 1-3 testpoints, when i press test again shows me capacitor in 2-3.
I built another ardutester on different arduino but this time every wire is soldered to arduino, and i have the same problem. first one was on nano v3 and 2nd one on mini pro.
self test is asking me for short circuit and when I do it after few seconds there is error on the screen.
checked connections and everything is as should be.
btw it's v0.7f sketch

Rambling around the Internet trying to catch-up on my reading, I found myself on the Ops webpages:
http://www.pighixxx.com/myblog/ (http://www.pighixxx.com/myblog/)

As of October 17, he was still alive and blogging.  However, his Ardutester page seems to be unedited for some time: http://www.pighixxx.com/tag/ardutester/ (http://www.pighixxx.com/tag/ardutester/)

Early versions of the port seemed to work OK but the embellishments eventually caused the software which is available in the #1 post to be unstable - in my case, unusable.  I see that others have had similar "weird" results, too.

I am wondering if this is just one of those projects that comes out kickin' and screamin' but dies before it is finished?

Bonjour,
Merci de votre travail.
Quelques erreurs de mesures m'ont été données.
J'ai intercalé un potentiomètre entre le  5v et GND le point milieu raccorder à la broche AREF.
Les erreurs ont été corrigées avec une tension de 0.84V.
Est-ce une bonne ou mauvaise idée?

En vous remerciant par avance.

Hello,
Thank you for your work.
Some measurement errors were given to me.
I inserted a potentiometer between 5V and GND the midpoint connected to the AREF pin.
The errors have been corrected with a voltage of 0.84V.
Is this a good or bad idea?

Thanking you in advance.


@Petruce,
I no longer have my tester on the solderless breadboard.  If I get some free time, I'll will try repeating your suggestion.
Thank you,

Ray

Is it perhaps not zeroing out the stray capacitance correctly?

Can anyone provide links for the latest schematic and firmware (sketch)?
It seems pighi's web site is  down for a long period of time and all the links are dead.

I gave up on the code because it had too many issues.  The older code worked OK but the rewrite did strange things, documented elsewhere.  Even when the site was up, only the most recent code was available.

Hi,
I have a couple of versions, but which one would you recommend me trying?

Thanks

Gee, hard to say... Go to the oldest and try that, if it works OK, then move forward in time.  The damage I noticed showed up with diodes getting misclassified and even the anode/cathode getting swapped sometimes... Also, some weird menu problems but I cannot remember the specifics.

Hi everybody.

As i started looking into this, i found news which i feels deserve to be mentionned in this thread.

Actually the project from which pighixxx based his ArduTester is very up and alive.

It looks very well maintained by Karl-Heinz Kübbeler and other contributors at http://www.mikrocontroller.net/articles/AVR_Transistortester#Introduction_.28English.29 .

The SVN accessible there shows at least 2 current versions, with many screen options :)

As the project seems quite mature, i might assemble mine sooner or later. Big thanks to all contributors !
