 - USB extension cable
 - light dependent resistor such as GL5528 (specific part number may vary)
 - 10k ohm resistor (resistance value may vary)

 the USB's green wire to pin 1/GP0 and USB's white wire to pin 2/GP1. You will
 also need to connect the red to 5V VBUS/VSYS (since you'll be powering from the
 USB host device, VBUS should be fine) and the black to any ground pin. Pin 38
 is the closest and most convenient. While you can connect the Raspberry Pi Pico

 you have already sacrificed half of the USB extension cable, you might as well

 then simply connect the red and black wires of the male connector end to
 VBUS (5V) and GND, respectively. For the data wires, you can solder them to the
