In this two tutorial we will Transmit data from an Arduino to another Arduino using the RF 433Mhz Module
Wiring Instructions
To wire your RF link Transmitter to your Arduino, connect the following pins:
- Connect the VCC pin to 5 Volts (5V)
- Connect the GND pin to ground (GND)
- Connect the ATAD pin to Arduino 12
To wire your RF link Receiver to your Arduino, connect the following pins:
- Connect the VCC pin to 5 Volts (5V)
- Connect the GND pin to ground (GND)
- Connect the ATAD pin to Arduino 12
Finally attach a small piece of wire at the ANT pin on the Transmitter to work as a small antenna
Required Hardware
Recommended Software
- Virtual Wire library
- Arduino IDE
Instructions and Code
Upload the first code to Arduino with the Transmitter and the second code to the Arduino with the receiver. Then open the serial monitor using the port of the receiver Arduino.If you need greater transmission range you may use a longer cable for antenna.
