Hello, as-salamu alaykum warahmatullahi wabarakatuh. So today I have created a new project, namely a microbit smart trash bin. This is a smart trash can, so when we bring our hand close to the sensor on the smart trash bin at a distance of 4 cm, the trash can lid will open. I will explain the components used: there is an ultrasonic sensor, a microbit, jumper cables, and a servo. Okay, for more details, you can watch the video below.
