Litar serta kod ini boleh digunakan untuk mengawal apa2 sahaja berdasarkan condition base yang diberikan oleh digital input daripada sensor.
Boleh menggunakan apa2 sensor seperti Flame Sensor, Infrared Sensor, Ultrasonic Sensor, Hall Sensor, malah suis mekanikal seperti Roller Micro Switch juga boleh.
Output boleh digunakan untuk menyalakan LED, membunyikan Buzzer atau memandu Relay untuk mengawal fungsi lain yang lebih besar seperti pam, spotlight, solenoid dan sebagainya.
Kod diubahsuai daripada "Pushbutton"
Sesuai digunakan untuk pengenalan dan mempelajari fungsi asas kawalan menggunakan Arduino.
// Turns on and off a light emitting diode(LED, buzzer, relay, etc connected to digital pin 13,
// when digital signal is present at pin 2.
// The circuit:
// - Output connected to pin 13 and GND return Input from any sensor signal connected to pin 2 for auto trigger
// - pushbutton attached to pin 2 from +5V and 10K resistor attached to pin 2 from ground for manual trigger
//- Note: on most Arduinos there is already an LED on the board
// attached to pin 13.
