Principle of Work:

The Beetle microcontroller works like Arduino, running programs uploaded through the Arduino IDE. It interacts with sensors, motors, lights, and more using its I/O pins. Arduino’s open-source ecosystem provides tutorials, libraries, and examples suitable for both beginners and advanced users.

Benefits of Pins, WiFi, and Bluetooth:

  1. Pins: The four analog and four digital pins allow connection to sensors, actuators, UART, and I2C devices.
  2. WiFi: Enables IoT applications, cloud communication, remote monitoring, and internet connectivity.
  3. Bluetooth: Allows wireless communication with phones, tablets, and other modules for remote control or data transfer.

Applications:

  • Sensor Integration
  • Actuator Control
  • Internet Connectivity
  • Wireless Communication

  6. Automatic Pill Dispenser
  7. Water Level Meter
  8. IoT Projects

Circuit:

No circuit needed; we will blink the onboard LED.

Connecting the Board:

  1. Connect Beetle BLE to PC via USB
  2. Download and install CH340 driver
  3. Open Arduino IDE
  4. Add ESP32 Boards Manager URL
  5. Select FireBeetle ESP32 board
  6. Select COM port
  7. Upload your program

Code:

// Blink LED on pin D9
void setup() {
  pinMode(D9, OUTPUT);
}

void loop() {
  digitalWrite(D9, HIGH);
  delay(1000);
  digitalWrite(D9, LOW);
  delay(1000);
}

Explanation:

  1. setup(): Runs once, sets D9 as output.
  2. loop(): Turns LED on/off every second.
