Peron Peroff machine
Useless machine, a device with a function but no direct purpose, started by the italian artist Bruno Munari in the 1930s.
Circuits
This version was mounted over an old Cigar box with Arduino Nano, a strong Mg996 servo motor, a 3d printed arm, DFPlayer mini, microSD, 4ohm 3 watts Speaker, a resistor and a switch.
Inside useless box
Art, philosophical point, sad metaphor, simple joke. All valid options.
CodeThere is not much code to explain. Just switch detection, servo movement and mp3 playback.
int butValue = digitalRead(switchPin);
if (butValue==0){
Serial.println("Machine is on");
// Play mp3
if (isPlaying==1){
// continue
play();
}
else
{
// first time playback
execute_CMD(0x0F,0x01,0x02);
isPlaying=1;
}
// Wait
delay(3000);
Serial.println("Move arm");
servoMotor.write(180);
delay(1000);
Serial.println("Return arm");
servoMotor.write(0);
// pause mp3
pause();
delay(2000);
}
