VMB8PBU CH (-) -------------- OPTO-COUPLER -
R1 = 220Ohm
C1 = 330uF
OPTO-COUPLER = Either a standalone opto-coupler as a switch (must have very low current draw) or an opto-coupler on a
relay board (e.g. Elegoo Relay board) with a JD1-VCC jumper so the inputs can be configured to power the opto-coupler
(high input) rather than low input
