· Home Automation with Bluetooth Module HC-05: o Components: Ø Arduino Mega 2560/UNO (x1) Ø Bluetooth Module HC-05 (x1) Ø Bulb (230V AC) (x1) Ø AC Supply (230v, 50Hz) Ø Relay Card (5V DC) (x1) Ø Jumper Wire (As per required) o Circuit Diagram: o Connections: Ø Take one Arduino Mega 2560/UNO, Bluetooth Module, 5V DC Relay Card and One 230v Bulb. Ø Connect Bluetooth module HC-05 with Arduino Board, Connect VCC terminal of HC-05 To 5V Terminal of Arduino board then connect GND terminal of HC-05 to GND terminal of Arduino then connect RXD pin of HC-05 to Tx0 Pin of Arduino and TXD pin to RX0 pin. Ø Now connect the VCC terminal of Relay Card with 5V terminal of Arduino board and GND terminal to GND terminal of Arduino and connect In terminal to 2 Pin of Arduino because here i take 2 no pin as a output. Ø Now give 230v Supply to common (C) terminal of the relay card and from Normally open (NO) Terminal give
