Prototyping a BBQ pit controller. Hopefully, updates coming soon. This project uses a Arduino micro. The Arduino reads a thermistor and adjusts a servo-motor using a PID controller. The K-values are set using trim-pots for now. I might pull those once I get the K-values tuned in. The servo-motor will control the intake flue, which controls combustion and intern temperature.
Finished soldering up the prototype board. I even have it running off a 9v battery through a buck power supply. I should get long life out of the 9v; I can use a wall wart if needed. I still need to solder up the controls put it in a box and rebuild my damper setup. Hopefully, I will get to cook some chickens this weekend and test everything out.
