Cut, splice and tin two pieces of wire.

Solder the wires to the button. The wires should be soldered to leads diagonal from each other.

Apply heat shrink to the button's solder connections.

Solder one wire to the QT Py ESP32-S2's GND pin. Solder the second wire to pin A0.

Tin the traffic light's four wires.

Insert the traffic light's wires through the 3D printed case's mounting hole.

Solder the traffic light's wires to the QT Py ESP32-S2:

• Black wire to board 3V
• Red wire to board A1
• Yellow wire to board A2
• Green wire to board A3

And that completes the wiring!
