Introduction: Computer Sensor

By

Supplies: Google Slide, Ultrasonic sensor, circuits, computer

Step 1: Circuit

Please follow the picture to complete your circuits. However, you can decide where the Ultrasonic sensor is. The D pin can change. For example, you can change D1 to D2 but you must connect the GND.

Step 2: Code&Measured

There's something you have to notice. The ultrasonic sensor's circuit that you connect must match the code that you make. Otherwise, your code won't work.

Step 3: Create a Slide Which Contains Warning Words in the Another Table

Step 4: Finish

After finish your code, you can test your machine. Theoretically, your computer will change to the other table you make automatically when you approach the Ultrasonic sensor.
