@MasMat I was purely wanting to find a way of testing them, to check my wiring, if they do come on during boot then this is a great way to test. It would also possibly be useful (for those of us less experienced) to have a script to run to check the wiring is correct. I think it much more useful to have them off, and blink on, and it was the wiring that confused me. I will have to see if I can investigate this further.
Iām sorry if this is a newbie question. I have managed to create a controller using MyController on a Raspberry Pi. I have connected a NRF24l01 and created a gateway, and my controller picks up that I have a gateway present, so I assume my wiring is correct.
I have started to wire up the status LEDs, and this is where I am confused. I am used to using LEDs on PI, but connecting between he GPIO pin and ground, where the GPIO provides the voltage. The diagram above suggests that they should be permanently connected to the voltage and the GPIO provides the ground connection. Is this correct? And if it is, is it possible to test the LEDs? Thanks in advance.
