Bluetooth Relay Control Step:2

Arduino Bluetooth Appliance Control

Step 2:

Relay Connections to Arduino Board

1. Connect GND to Arduino GND
2. Connect RL1 to RL4 to Arduino Pins 9,10,11,12

Step 3:

Connect Power to relay board using M-M Connecting Wires

1. Connect GND to Arduino Ground
2. Vin/ +12V to Arduino Vin

 Connect Bluetooth Module:

1. Connect Bluetooth module GND to Arduino GND
2. Connect Bluetooth module VCC to +5V of arduino
3. Connect Txt of Bluetooth module to Rxd (0) pin of arduino
