Introduction: 3-ways to Controll Home Appliance

Picture of 3-ways to Controll Home Appliance

This project is done to controll your home appliance.

Generally we controll our home appliances manually using general switches.

But now using this project we can controll it in 3 ways

1) Manually

2) Rf Remote

3) Bolt

what we need to built it is

Component list

1) IOT BOLT

2) RF 434 MHz TRANSMITTER - RECEIVER

3) HT12E Encoder IC

4) HT12D Decoder IC

5) Resistors – 33k,750k

6) 220 ohm Resistors – 4

7) Push buttons – 4

8) SPST switch – 1

9) LEDs – 5

10) 5v relay-4

Step 1: Start Soldering

Connect the circuit components.

Step 2: Check the Circuit

Picture of Check the Circuit

Apply 5V supply to the transmitter and receiver sections. Now you can observe that all the LEDs at receiver will glow.

Step 3: Connect IOT Bolt to Transmitter Circuit
