16  Using Arduino / Microcontrollers / [SOLVED] avr to breadboard help? on: March 17, 2013, 07:57:08 pm
HI all,
 I have an arduino UNO, with the atmega 328p-pu micro-controller.  I am trying to use the tutorial: Minimal Circuit (Eliminating the External Clock)
 but I persistently get errors, such as:
avrdude: stk500_recv(): programmer is not responding
I have avrdude installed.
I use Linux, and have tried versions 1.0.3 and 1.5.2 of the sketch compiler.
The breadboard file is in:

The programmer is set to Arduino as ISP.
the board is set to ATMEGA328 on breadboard (8MHz internal clock)

When trying to burn the boot-loader I get:
avrdude: stk500_recv(): programmer is not responding

When trying to just compile a sketch I get:

In file included from sketch_mar17b.ino:1:
/home/user/sketchbook/hardware/arduino/cores/arduino/Arduino.h:213:26: error: pins_arduino.h: No such file or directory

Which I understand, the pins_arduino.h header isnt in the /home/lol/sketchbook/hardware/arduino/cores/arduino/ folder... but what pins_arduino.h file am I supposed to use?

What I want to do is use the arduino as an ISP.
I'm getting confused... do i need 2 micro-controllers to burn a boot loader on to one?
(looking and comparing:

can some one please extent some help to me? I cant believe Im the only one having these problems, but I haven't found a solution I can understand yet.
17  Products / Arduino Due / v 1.5.2 compiler issue on: March 11, 2013, 12:05:53 am
Hi all,
I am just reporting that I had problems in the 1.5.2 version compiler with the breadboarding tutorial. My problems were solved by reverting to version 1.0.3.   reference posts:,153510.0.html

Wow, Ok.
I switched to compiler version 1.0.3 and the tutorial worked.
Problem solved. Thanks James.

I read the datasheet to verify the compatibility of the instructions to the chip.
I did assume that the 1.5.2 compiler was compatible with the UNO board, since I have been using it to program the UNO for a week or two without problems.

many relays had a set of NO contacts and the alternate set of NC contacts. Depending on the relay you have, it would be entirely possible with 1 relay.
If your relay only has 1 set of NO contacts, then you cant do it with the relay alone.

21  Using Arduino / General Electronics / Breadboard [solved] on: March 10, 2013, 11:18:01 pm
Hi all, I am trying to use the tutorial
which elimates the external clock.
I am using an arduino UNO, on a Linux platform, with the 1.5.2 version of the compiler.
The 5th line of the section: Minimal Circuit (Eliminating the External Clock)

I never get to see:
You should see "ATmega328 on a breadboard (8 MHz internal clock)" in the Tools > Board menu.

at this point, I am getting confused, and frustrated, I have read the atmega 328 data-sheet, and looked for other tutorials, but it is just not working.
can anyone help me out here?

22  Using Arduino / General Electronics / Re: Do you have any tricks for identifying chips? on: March 10, 2013, 11:09:37 pm
go find the data sheet.
traditionally, putting an diode checker from gnd to vcc will test good at ~0.7V -- ~1.4v rev bias. Short is indicitve of short, OL indicates open.
not all chips test like that, but ma

family | Device | specific
ps           224         u
74         LS00        n

some chips are proprietary, like black-boxes, some manufacturers use part numbers that overlap other manufacturers components.
sometimes looking for a chip, you cant find the exact number, so you can truncate the last few digits, like anything after a dash, to find the chip family data.
23  Community / Website and Forum / Playground editing Netiquitte? on: March 04, 2013, 09:34:52 am
This page:

has an example that is non-functional as is. I want to edit that page so that the example code functions in the modern version of the compiler.
I didn't see anything about commenting out things in the wiki about editing.  I am also not sure about the protocol of editing a page. I understand
that I should sign my changes, but should I also date them, and do that line by line, and explicitly note what i have changed?

Also, how do I insert comments which cannot be seen in the non-editing mode of the wiki?
24  Topics / Device Hacking / fuse-map from a PAL? on: November 20, 2012, 01:14:55 am
Hi all, I have an ancient device that I am mapping out a schematic for. The bulk of the device is shift registers, but  there are also 4 Programmable Array Logic devices. (PAL16L8ACN)
Does anyone here have any experience generating fuse-maps from existing PAL ICs? I do not have the original Fuse map, and as of yet, i have no idea how to determine the setup of these devices.
Anyone have some tips?

Solved! smiley Thank you.
26  Using Arduino / Project Guidance / ISA to usb converter on: November 08, 2012, 11:12:26 am
Hi all,
I want to interface an arduino uno to an ISA port device, and output to the USB port, or Ethernet if possible.  The device is a proprietary 16bit spectrometer, to which I do have the driver for... its intended for windows 98.
The idea is to have users be able to log into their FTP server, via some sort of interface, and press 1 button to take spectra.
I would like it to not even require a computer, but I am not sure if that is possible.
I have about 200-500$ to work on this if that might entice anyone.

I wanted to buy this:

but they are no longer in production.
27  Using Arduino / Project Guidance / Re: Project: sensor that triggers a stepper motor on: November 08, 2012, 07:48:44 am
Bipolar or unipolar stepper? (I hope you dont mean a servo mechanism)

there are tons of driver ICs out there now that make this task a matter of: a sensor, a PWM, an enable disable, and a directional flag.
I had a real nice one a few years back I gave it to a friend, and don't recall the part number. smiley-sad
But, I usually look for Maxim ICs because they do parts sampling.. (free parts for students and development engineers! woot!)
A chip like the one at this link:

is what I am thinking of. many exist.  Its an H-bridge.

This link I thought was a nice block diagram, with a unipolar stepper configuration
28  Using Arduino / Project Guidance / arduino + usb webcam? on: November 08, 2012, 07:35:37 am
Hi All,
I have a software I am working on that takes spectra based on image data. What i want to do, is deploy my spectrometers remotely, and collect image data for a while.
I have an arduino Uno, and the SD card / Ethernet shield. I want to set up the usb web-cam to periodically take a picture of a fixed size, and quality, and save it to the SD card, with a time stamp(?) is this possible? Can someone give me some leads?

I saw the posts on the cmos cam thing... that was useless. Please don't point me there.
29  Using Arduino / Project Guidance / Re: Arduino to control a plasma cutter??? on: November 08, 2012, 07:22:30 am
Ive done quite a bit of mods similar to which you speak.
1, it would be easier to design a replacement if you had a working model.
2, I would try to utilize the existing hardware as much as possible.

there are other issues that you may well encounter. Like current problems, if the control IC can source more than the arduino. 
The section 5.3 in the attached PDF looks helpful for a programing an alternate device, the figure is briefly describing operations.
That schematic is nice too! I would test that circuit some more though. What caused the previous device to fail?
30  Using Arduino / Programming Questions / Re: cmos camera + arduino uno on: November 08, 2012, 07:09:00 am
I am planning the same thing, but will utilize the SD card memory option.
Though I may also try using a webcam, and try interfacing it.
