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.

Don't know what all the costs are for a setup of this nature , but if it is as good or better than a say Dakota Digital at a reasonably priced deal , I would be interested in the final results. Having all 4 CHTemps at display would be a great engine monitor ( one of the priority things to keep an eye on ) to have . Would the microcontroller have the capabilities to read / display AF ratioes with O2 sensors or am I dreaming ??? (IMG:style_emoticons/default/unsure.gif)

I think that is a pretty reasonable price for a 4+ channel TC display. And yes, AF rations have been done with the arduino, as well as EGT. At the beginning of the second code, shows where to get the AD boards and a punch out of parts. About 15 bucks per channel for thermocouple. O2 sensor would be pretty easy, since they are already an analog voltage output. My megasquirt gives me that data already, do probably not something i'll put in the code. |
