Arduino project for receiving and (in the future) transmitting signals using a 433 MHz RF module.
Currently, this repository contains code for a 433 MHz signal receiver, which allows reading signals from wireless remotes, sensors, and other RF transmitters.
- ✅ Reads signals from 433 MHz RF remotes
- ✅ Displays received codes in the Serial Monitor
- ✅ Supports ASK/OOK modulation
- ✅ Uses rc-switch library for easy decoding
- 🔜 Future update: 433 MHz signal transmission
- 🏷️ Arduino-compatible board (e.g., Arduino UNO, ATmega328P)
- 📡 433 MHz RF Receiver (AM ASK/OOK)
- 🔌 Jumper wires
- (Optional) Antenna (~17 cm wire) for better range
| Receiver Pin | Arduino Pin |
|---|---|
| VCC | 5V |
| GND | GND |
| DATA | D2 |
- Install PlatformIO
- Upload the Code to your Arduino
- Open Serial Monitor
When pressing a button on a compatible remote, you should see:
433 MHz Receiver is ready
Received signal: 123456
Received signal: 654321
If no signal appears, check:
- 🔧 Wiring (ensure DATA is connected to D2)
- 📶 Antenna (use a ~17 cm wire for better range)
- 🔄 If your remote ASK/OOK compatible?
- Add 433 MHz transmitter support
- Implement custom protocol decoding
- Integrate with smart home automation
