<title id="t">Johnny 5 wiring pinout - both ESP32 boards and both LED circuits</title>
|
|
<desc id="d">Board A runs Bluepad32 and pairs with the PS4 controller. Board A GPIO17 goes to Board B GPIO16; Board A GPIO16 goes to Board B GPIO17; the grounds are joined as a shared reference. Board B runs Legoino, connects to two LEGO hubs over BLE, and drives two independent LED circuits: GPIO25 through a 220 ohm resistor to the red LED pair and back to a ground rail, and GPIO26 through a 100 ohm resistor to the green LED pair and back to the same ground rail. Each LED has its own complete path; they are never in series.</desc>
