Example code

void setup() {
  Serial.begin(9600);
  Ethernet.begin(mac, ip);
  btSerial.begin(9600);
}

void loop() {
  if (btSerial.available()) {
    char command = btSerial.read();
    switch(command) {
      case 'A': digitalWrite(A0, HIGH); break;
      case 'B': digitalWrite(A1, HIGH); break;
      case 'C': digitalWrite(A2, HIGH); break;
      case 'D': digitalWrite(A3, HIGH); break;
    }
  }
}

Mini project

Design an intelligent lighting system that automatically activates when it detects motion and adjusts the intensity based on external light. Use the control board to control the relays and the Android app for configuration.
