void setup() { Serial.begin(9600); bluetooth.begin(9600); }
The JDY-40 is a Bluetooth 4.0 module that uses the UART (Universal Asynchronous Receiver-Transmitter) protocol for communication. It has a maximum data transfer rate of 1 Mbps and a range of up to 30 meters. The module is powered by a voltage range of 3.3V to 5V, making it compatible with most Arduino boards. SoftwareSerial bluetooth(2, 3); // RX, TX The JY-MCU
void loop() { if (bluetooth.available() > 0) { char data = bluetooth.read(); Serial.print("Received: "); Serial.println(data); bluetooth.print("Hello from Arduino!"); } } This code sets up a software serial connection using pins 2 and 3 for the RX and TX lines, respectively. It then reads incoming data from the Bluetooth module and prints it to the serial console. The Arduino board also sends a response back to the Bluetooth module.
