I made a PID controller that uses a SSR to drive a resistive load (heating coil), a type K thermocupple with the adafruit max31855 breakout board. I'm using the adafruit max31855 lib with the arduino PID and PID front end libraries. I have the set point at 100*C, when I turn it on at room temp the r…
