 ### Hardware
 
 You will need the following hardware to make the device:
 - Raspberry Pi Pico W
 - USB extension cable
 
+![Wiring of USB connectors to Raspberry Pi Pico W](diagram.png)
+
 You will need to cut the USB extension in half and connect the wires from the
 female end to the Raspberry Pi Pico W. The default configuration is to attach
 the USB's green wire to pin 1/GP0 and USB's white wire to pin 2/GP1. You will
