Picaxe microcontroller project: thermostat. The serial 7 segment display (from Sparkfun) shows actual temp in Fahrenheit. Setpoint adjusted with the potentiometer on the right. (display alternated between showing setpoint and actual temp) The microcontroller is the Picaxe 18X in SOIC form on the bottom, temp sensor is the Dallas 18B20, mounted on the wires to the right. Heater is controlled by an Omron 653-G3MB-202P4DC5 solid-state relay (black box left of 7 segment display).
