The circuit is so simple and small, there are only a few connections to be made Arduino Pins Bluetooth Pins RX (Pin 2) ———-> TX TX (Pin 3) ———-> RX 5V ———-> VCC GND ———-> GND Connect a LED negative to GND of Arduino and positive to pin 13 with a resistance valued between 220Ω – 1KΩ. And you\'re done with the circuit
