I have a string of 3 730nm 5v leds, which I've hooked up in a circuit with an led driver AND a small programmable timer. Last grow the circuit worked fine for a couple of months until it stopped working. It turned out to be a fault with the middle led, and I assume the other two are fine.
Now, the question is how I can measure the circuit with a multimeter?
The bad led has been replaced and I'm about to use the exact same circuit for this next grow, but I'm having a hard time figuring out what the programmable timer does to the circuit and if something is gonna break again.
