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
2) Rf Remote
what we need to built it is
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
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
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
