I purchased the Menard's multipurpose/multisign building and the duplex. Mr. chessiechick intends to use some wall warts that we already have to power these buildings instead of purchasing the Menard's power supply.
When looking at the multipurpose building, we found a circuit board. (We haven't unboxed the duplex yet.)
If I understand correctly, these buildings are designed that the lights simply turn on and off, so what is the purpose of the circuit board?
