Low power consumption
Compact designPinoutVCC: Power supply (typically 3.3V or 5V)
GND: Ground
DATA1: Data input for Channel 1
DATA2: Data input for Channel 2
ANT: Integrated antennaCode Examples### Example 1: Basic Transmission using ArduinoIn this example, we will use the 2CH 27MHZ with Antenna module to transmit two separate signals using an Arduino board.```cpp
#include <RF27MHz.h>#define DATA1_PIN 2
#define DATA2_PIN 3RF27MHz transmitter(DATA1_PIN, DATA2_PIN);void setup() {
Serial.begin(9600);
transmitter.begin();
}void loop() {
// Transmit signal on Channel 1
transmitter.send(1, 0x01);// Transmit signal on Channel 2
transmitter.send(2, 0x02);delay(1000);
}
```### Example 2: Wireless Communication between Two Arduino BoardsIn this example, we will use two Arduino boards, each equipped with a 2CH 27MHZ with Antenna module, to establish a wireless communication link between them.Transmitter Code
```cpp
#include <RF27MHz.h>#define DATA_PIN 2
RF27MHz transmitter(DATA_PIN);void setup() {
Serial.begin(9600);
transmitter.begin();
}void loop() {
// Transmit signal on Channel 1
transmitter.send(1, 0x01);delay(1000);
}
```Receiver Code
```cpp
#include <RF27MHz.h>#define DATA_PIN 2
RF27MHz receiver(DATA_PIN);void setup() {
Serial.begin(9600);
receiver.begin();
}void loop() {
if (receiver.available()) {
byte data = receiver.read();
Serial.print("Received data: 0x");
Serial.println(data, HEX);
}
}
```Note: In this example, the transmitter sends a signal on Channel 1, and the receiver listens on the same channel to receive the data.These code examples demonstrate the basic usage of the 2CH 27MHZ with Antenna module in different contexts. The module can be used in various applications, such as wireless sensor networks, remote control systems, and IoT projects.
