Hi,
As we can learn for the others stupid errors. Let me explain my last work. The goal is to sold button with built in led on a pcb (rec, solo etc buttons). For the DIN, I’ll retry later : first attempt, 1st short circuit. Happily the 7805 is protected !!!
So I soldered 16 buttons on the pcb. Ok, first try, every leds are soldered in the wrong way … Desolder, retry again: good. Then I tested the pushbuttons : Guess what ? I soldered them the wrong way too (4 pins connected 2 by 2).
So for next time, I’ll begin with ONE button and then test (not at the end).
Good midiboxing, Steph keeping believing
