Connecting our Pi Zero

Now that we have our electrical circuit, we need to find a way to attach our Pi Zero to each pair of LEDs and the common ground we have sewn into our garment. We are going to make use of the poppers we stitched onto our hidden pocket for this. You have probably noticed that the only piece of conductive thread, which we attached the male popper to, was the common ground thread for our LEDs. This is so that when we construct our method of attaching the Pi Zero GPIO pins to the conductive thread, it will be impossible to connect the positive and negative threads the wrong way round! Another reason for using the poppers to attach our Pi Zero to the conductive thread is because the LEDs and thread I am using are both rated ...
