Like this?: http://www.youritronics.com/attiny2313-temperature-controller/ http://www.atmel.com/dyn/resources/prod_documents/doc2529.pdf The problem is in finding the code to get the AVR to do what you want. If you can write the code, your good to go. Many of the AVR's have the analog input, PWM, digital and serial output that would be needed. The AVR has enough processing power to do PID or other control intelligence in software. My approach would be to find the code from examples on the Internet that covered the features I wanted, then combine the code in my application. ~~~~ I just read Jon's comment and found a lot of controllers on eBay in the $40 or less range. This may be the way to go if a PC connection isn't required. I have a vision that the smoker is outside in the snow and being able to check the temperature from inside might be desirable? I have to admit that because I have a new hammer, everything I see looks a bit more like a nail. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ Lotusphere 2011 Register now for Lotusphere 2011 and learn how to connect the dots, take your collaborative environment to the next level, and enter the era of Social Business. http://p.sf.net/sfu/lotusphere-d2d _______________________________________________ Emc-developers mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-developers
