This is another experiment. It’s an automatic controller for the hive heater I installed. The light sensor on top is programmed to only come on from dusk to dawn. Below that is a temperature block that comes on at 35 degrees and goes off at 45 degrees. The heating pad is plugged into the temperature block. I also plugged a nightlight into the temperature block so that I can look out from the house and see if this thing is on.
