Arduino Bluetooth Relay Control Code

 

Arduino Bluetooth Relay Control Code

Simple Arduino Bluetooth Relay(Single Relay) Control Code is discussing in this project

Components Used

» Arduino Uno

» HC 05 Bluetooth Module

» Relay Module ( Single Channel)

» USB To DC Jack Converter

» Power Supply - 5 volt 

 : The recommended power supply given to the Arduino DC Jack adapter is 

12 volt DC with an ampere of 2 Amps.

Step 1 - Connect HC 05 Bluetooth Module To Arduino Uno

» Bluetooth 5 V is connected to ICSP pin Vcc.

» Bluetooth gnd is connected to ICSP gnd pin.

» Bluetooth TX pin is connected to Arduino pin 0

This is shown in the above figure.Positive of icsp is on top most right of arduinio board.The ground pin of icsp is bottom rightmost corner of arduino uno board.

Step 2 - Connect Relay To Arduino Uno 

» Relay 5V is connected to Arduino 5 V.

» Relay gnd is connected to Arduino gnd.

» Relay in is connected to Arduino pin 3 labelled on arduino uno board.

Step 3 - Light Bulb Wiring Connection To Relay

» The light bulb wiring is shown above

» Here above figure the two stripped wires should be given to the relay.

Step 4 - Connect Load / Light Bulb To Relay

» The above figure shows how the two wire points are connected to relay.
