TRASH-BOT. (ARDUINO AUTO OPEN CLOSE TRASH BIN) Everything's getting smarter right? So why not your Trash Bin? This trash bin Opens and Closes its lid if it sees any Rubbish in front of it. You just need to bring the rubbish to it and it'll open automatically and will wait for you to feed it more then after a certain delay it'll close automatically. Watch the video to see exactly what it can do. Let's get started. Step 1: Parts You'll Need 2 More Images 1.Arduino (any board) 2.Servo motor (i'm using micro servo sg90) 3. HCsr04 ultrasound sensor 4. Servo arms (beside the servo in pic2) 3. Card Board (just slice piece) 4. Trash Bin Step 2: Build the Circuit The circuit is so easy. As the servo and sonar only takes less power you can just power them directly from arduino 5v source. Just remember to power the Arduino with more than 7.4 V DC or at least 7v.
