Touch-free smart dustbin
BeginnerBuild time 1–2 hours· You'll learn: Arduino, Ultrasonic sensing, Servos
A favourite school science-fair build. An ultrasonic sensor on the front of a bin notices a hand within 20 cm, and the Arduino swings the lid open with a servo, waits a few seconds, then closes it. It teaches distance sensing, servo control and timing in about an hour.
