Connection Guide
Receiver pinout:
- VCC: 5V or 3.3V
- GND: Ground
- DOUT: Digital output (to MCU)
To Arduino:
- VCC: 5V
- GND: GND
- DOUT: Digital pin (e.g., D11)
To Raspberry Pi:
- Use 3.3V for VCC
- Connect DOUT to GPIO pin
- Use appropriate resistor if needed
Install the IRremote library for easy decoding
Point remote directly at receiver for best results
Do not exceed 5V on VCC for 3.3V systems
Avoid sources of IR interference
Programming Instructions
For Arduino:
- Install IRremote library via Arduino IDE
- Use example sketch to read IR codes
- Map codes to remote buttons
- Use button codes for your project
Common IRremote functions:
- irrecv.enableIRIn() - Start receiver
- irrecv.decode(&results) - Decode signal
- results.value - Returns IR code
- irrecv.resume() - Ready for next signal
Remote control format:
- NEC protocol (standard)
- Each button sends unique code
- 21 keys available for control
Easy Decoding - Library handles all timing
Reliable Reception - Good sensitivity and range
Works with all Arduino boards
Compatible with ESP8266 and ESP32
Troubleshooting
No signal received:
- Check receiver connections
- Verify IRremote library installed
- Avoid bright light interference
Wrong button codes:
- Press button slowly
- Check library version
- Avoid multiple presses
