This cabling is of course only true for the first 3 devices (not the WS2812). To check the device we can temporarily connect these pins to Vcc (make sure the current limiting resistor is there, either in the breakout board or externally added by you) in which case we should see the corresponding color come up on the LED. Once connected to the gpio pins we can start programming.

Making a LED light up is one of the most simple programming exercises possible and therefore ideally suited to get us going with Python programming.
