Step 2: Connecting Servo Motor
First, I will start with the mechanism to open the lid. In order to open the lid,Glue one end of the popsicle stick to the flat side of the servo's horn. It must be palced near the hinge where the lid is connected to the main can.
Step 3: Programming
Connect the arduino and upload the given program on your arduino uno.
Step 4: Wiring
You can place Arduino, Sound Sensor, Mini Breadboard, and 9 Battery on Dustbin with the help of double tape and Wire the circuit as shown in the picture.
Step 5: Testing
Test your whistle to open the dustbin.
