My very first Arduino micro controller program. I've never used the Arduino language before ( think it c or C+ ? ) anyways, took me a few hours. Still need to order the thermocouple conversion chips, but looks like it will work. You can see when I put my finger over the analog pins, it does change as it should. Total cost will still be less than a single channel VDO gauge, and I will be able to calibrate it for more accurate readings.

Parts list
http://cgi.ebay.com/Arduino-Duemilanove-20...=item3f018b704f http://cgi.ebay.com/LCD-Keypad-Shield-Ardu...=item3f018b71d5 These are the TC boards, but I have a source for them on my PC at home, with a complete Digikey order page. Think the parts were $1.00 per board, and about $15.00 per channel for the AD chips and parts. http://store.makerbot.com/thermocouple-sensor-v1-0-pcb.html I have done nothing since with it other than order some boards, in the process of moving, fuel pump went south on the 914, and my Jeep is spewing coolant as fast as I can put it in. So right now priorities are, Jeep, 914, |
