This time I made a smart trash bin project. This is my third project in my 2nd semester. I didn’t make it alone. I was with my team, namely Tsaqif and Zikri. So, the way the smart trash bin works is if there is an object around the ultrasonic sensor, the ultrasonic sensor will give a signal to the servo, then the servo will open the trash can lid and the function of IObit is to connect the servo, ultrasonic and microbit.
