RF Communication using Arduino and MX-05V/MX-04V

Arduino Setup:

Arduino A (Transmitter):

• Connects to the MX-05V RF transmitter.
• Button connected to detect the press.

Arduino B (Receiver):

• Connects to the MX-04V RF receiver.
• Relay controlled by the Arduino.

Connections:

MX-05V (Transmitter):

• VCC to 5V on Arduino A.
• GND to GND on Arduino A.
• Data to any digital pin on Arduino A (let's say D3).

MX-04V (Receiver):

• VCC to 5V on Arduino B.
• GND to GND on Arduino B.
• Data to any digital pin on Arduino B (let's say D2).

Button on Arduino A:

• One terminal to GND.
• Other terminal to D4 on Arduino A.

Relay on Arduino B:

• Signal pin to D5 on Arduino B.
• Make sure the relay is rated to handle the load and voltage of whatever you're switching.
