In todays video we make a simple magic harp project via LDR, Lasers and arduino

Code:
const int LDR_PIN1 = A1; // Analog pin connected to the first three-pin LDR module
const int LDR_PIN2 = A2; // Analog pin connected to the second three-pin LDR module
const int LDR_PIN3 = A3; // Analog pin connected to the third three-pin LDR module
const int LDR_PIN4 = A4; // Analog pin connected to the fourth three-pin LDR module
const int LDR_PIN5 = A5; // Analog pin connected to the fifth three-pin LDR module
const int BUZZER_PIN = 9; // Digital pin connected to buzzer
const int LASER_PIN = 2; // Digital pin connected to laser diode
void setup() {

}

}

Yoo that’s craaaazy
