Introduction: 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
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
Connect to specific I/O pins
