  • Hi I need an help, it is not clear to me how to connect the wires... I am using a x-OSC board (3.3 V), not arduino. I connect the A to voltage, C to pulldown (10k resistor) and then to GND. In this way the led is always on.... What I am doing wrong? And how/where I connect B1 and B2? Thanks in advance

No public wish lists :(
