can you get hold on the type of LCD , i mean is it a Dot matrix, or dot matrix alphanumeric or which one? , depending on the type some steps may be taken or possible.

That's really Great TechONe
1158  Topics / Science and Measurement / Re: Android GPS to Arduino on: March 10, 2012, 12:13:55 am
I think here the best available thing would be write your Android App or Use the Amarino its opensource and it already configures android to send values to Arduino, so edit this code to add a GPS library in the code and implement storing of gps data in variables that can be then further sent via. Bluetooth to your arduino.This is the best because you have something to start with as you not start baseless , you atleast have a communicating facility with this option you just need to gather GPS data and send it using the respective library.

for this you need to have some development experience in Eclipse with JAVA only as c++/c is not supported as core modules under android development.
Even if you want to implement what MarkT is saying then also you need to develop in Eclipse or other Android supported IDE in mainly JAVA only.

Thanks a lot i already know about them and have always loved them, The only problem is that they aren't provided in india by any legal Distributor, as such i was thinking to take distributorship myself for these teensy's , there are total of mainly 8 distributors of arduino stuff in india out those 7 are located in South India(im very far from them in DELHI, north india courier cost hurt me as such) and none of them deals with Teensy's what a lame thing!

also the other Physical computing/Emdedded providers here also do not even talk about Teensy's and  i yet do not have Credit Card to make purchases offshore.

EDIT: Ebay allows me to pay in a manner other than CC, but i do not get Teensy on it????? rather TEENSY WEENSY GSTRING BIKINI babes turn up

1160  Using Arduino / Displays / Drive Multimeter(Dot M.ALpha) LCD type with Arduino! on: March 09, 2012, 08:30:56 am
Has anybody tried to programme the LCD's that are on the multimeter , I think they use graphic lcd's as they can draw on themselves images of ohm there any way? or anyone worked with them?

Where do you get the data from? (OBD?)

Im living in Germany.

This is the biggest part , here we have old technology bikes in India(New ones with ECU are being introduced but are costly and i can't buy one) which have carburettor and NO ECU so OBD isn't existent so as such i have my own sensor installation for reading magnet sensor and framed the Algorithm that calculates the speed and fuel gauge level and other things you have on screen and apart from this i have also used a CD4021 Shift Register here because i used a Deumilanove and because the GLCD ate up all the pin's on it.

The shift register is soldered on a board (SEE ATTACHMENT) with voltage dividers taking input from bikes 12v battery system and bringing down to 3-4 volts DC for getting functions like Indicators and neutral and a single button for TRIP meter,it also has a voltage regulator that intakes the variable power inputted to it from resistor that changes value on the basis of float level in fuel tank and is fed into ANALOG PIN or ATmega328.

The programme that i have right now takes a lot of space and it is currently 22KB on FLASH right now because there is custom font developed for it and other Graphics are there as well. other is the code.

Germany is a very high technology driven country i think you would be easily able to procure a GLCD there , may be it is available two lanes down to your home.just get to a electronics store and have it.

Make sure you ask for a Ks0108 Driver compatible GLCD as the library of GLCD is Ks0108 driver compatible ,however it is the most popular Driver that is on these GLCD's so definitely you will have it easily, Cost would be like 15 to 20 euros or 20 USD(there is one more driver with which the GLCD v3 library is compatible with but Ks0108 is so popular and widely on these GLCD's that you won't even have to care to know about it!)

Thanks so much for your comprehensive definition.
Actually im just having problem at the Opto-Isolator Traic connection with Power triac and final connection with wallwart power. The rest im receiving the pulses successfully , i checked that and its fine.

I liked your idea of using 12v ac power supply ,well it helps keep FIRE works in control and thus things just do not fire out at you.
1163  Using Arduino / General Electronics / Re: Changes in Dimming Circuitry! on: March 08, 2012, 10:41:09 pm
Thanks a lot sir, i will give you whole information about the TRIAC  and other things:

The OPTO Traic here is MOC3023 - 247Q  Vmax is 400V,ATTACHED - Datasheet

The Power TRIAC here im using is the BTA 12-600B , so 12 Amperes of power handling and 600 v max handling of current , i think is pretty nice solution, i also have a BT136 here.

I have found another very simple working circuit that also im attaching, please check it and tell should i use it for 220vac@ 50 hz here , i have modified the circuit to have 100K 1 watt resistors that i have checked definitely light up the LED in the 4n35 and interrupts happen flawlessly and im just caring about values to use in with the circuits resistor to be used at triac side , however im using 2 series 1/2 watt resistors that are about 1k.
1164  Using Arduino / Networking, Protocols, and Devices / Re: Problem in CODE for WiShield v1.0 on: March 08, 2012, 09:04:33 am
The apps-conf.h file you attached isn't any different than the one I already have with the 1.0 version. I'm still getting the same two errors.

I'm assuming you checked the file i sent but didn't used the 0022 IDE

The apps-conf.h file is not related with 1.0 version its just this that the way Arduino 1.0 IDE deals with the WiShield library is different the 0022 IDE deals with the same. so please use 0022 IDE with this WiShield implication. first try with 0022 IDE then if things are fine then in that case put the same code in IDE 1.0 and try to sort out things there.

Nice done.

Do you have more background-info?

Where did you got the LCD from and how much did it cost?

Hi Kduin ,Thank you very much for appreciation,
Yes i have more background-info , What do you want to know specifically, However i can provide you a step by step guide?
Where are you located?(Country)


I have loaded 2 more pic's which illustrate the change in Fuel gauge level on the screen as per the fuel in tank.
1166  Using Arduino / Networking, Protocols, and Devices / Re: Problem in CODE for WiShield v1.0 on: March 07, 2012, 11:47:13 pm
Got the code compiling with 0022 but with Arduino 1.0 still facing the following:

D:\Removable Disk\arduino-1.0\libraries\WiShield\WiServer.cpp:212: error: prototype for 'void Server::write(uint8_t)' does not match any in class 'Server'
D:\Removable Disk\arduino-1.0\libraries\WiShield\/WiServer.h:198: error: candidate is: virtual size_t Server::write(uint8_t)

never mind im using the 0022 to work with WiShield but to sharpen concepts it should be known that why this is causing problems in Arduino 1.0, Any one comes to know , Please make me understand as well!

If you refer to my above post as i quoted (look above for it in details) you will get to know that i solved the problem long time ago, please look above to solve these problems and use 0022 IDE not Arduino 1.0 it has some code problem's.


You just need 2 things to care here about:
1) Use 0022 Arduino IDE.
2) Replace the apps-config.h with the one i provided you in the attachment.

further you may contact me on if you aren't able to make it work.

Triac Blown and Fireworks were there

an inductive load does change the MOC and TRIAC scheme:

At this time im doing the same circuit but it isnt working for me yet

Attached you will find the Bread board connections(dn't be shocked by the tin wires running im duely taking care  smiley-grin)

Actually im facing problem  mainly at triac end with not correct connection of bulb ,so im going to use schema 1 of yours
