hello gays so this time I made a project or assembled a trash can, but this is not just an ordinary trash can, this is what we can call a SMART TRASH BIN, so the term is this is a smart trash can, why do I call it a raft, because if we want to make this smart trash can, of course we will make a hole or cut it, now in the smart trash bin there are 3 main items, namely Arduio uno, Servo, and Ultrasonic sensor, and the rest are jumper cables, for the coding it is very easy, we just use logic
