Traffic Light with Arduino sequencer for Power Hour

This is a LED Traffic Light with custom power bank and microcontroller (Arduino)-based sequencer I built.

The Arduino is seen on the far right, connected to the power bank (center) by ethernet cables. The power bank has 8 individually-addressable solid state relays that control outlets. One can override each outlet manually as well. Each color of the traffic signal has its own 120 V plug (normal household plug), which plugs into the power bank.

This Arduino setup can be programmed for any imaginable lighting sequence with up to 8 unique light channels. Christmas light displays (without music) are easy to implement with this setup as well.

I have the current sketch set to ‘POWER HOUR,’ whereby the lights cycle through once every 60 seconds. For the last 5 seconds of each cycle, the rope light and Christmas lights flash to give a warning. A strobe fires for the first 5 seconds of the cycle to make sure no one skips a round.
