This isn’t for an arduino, but for a relay control for lights at home that stopped working. I was hoping you folks can help me figure out what the problem might be.
When the power button is pressed, the relay switches, but turns off immediately. I replaced the relay with the same one hoping it was just a faulty relay, but the problem persists with the new one. My guess is that it’s another component on the control circuit that’s become faulty, but I have no clue which might be the culprit. I tested the switch with a multimeter and it’s working fine. The capacitors and resistors/diodes all look fine too.
The relay control takes in 220v (connected directly to the wires of an outlet). The relay is a DC12, so I’m guessing the circuit steps down the voltage.
The IC is HEF 4013BP (HEF4013BP datasheet(1/16 Pages) NXP | Tolerant of slow clock rise and fall times)
Now that I know it’s not a faulty relay, what could be causing a relay to not hold?
Any help would be appreciated.
