The AC power is switched to 3 outlets with BT136 triacs which are controlled by a microcontroller through MOC3023 optocouplers. Capacitors C1-C3 must be 400V compatible, and resistors R1-R6 must sustain 1W power dissipation. The triacs have small heat sinks.
As you might spot at the photo, I changed one of the triacs to a relay. It’s because I use a cheap fluorescent lamp for my aquarium and it doesn’t work via triac.
