ABOUT THIS PROJECT
YouTube Video
My project is about detecting things in a surrounding using ultrasonic waves.
Things used
- Arduino Nano
- Ultrasonic sensor
- Servo motor
- Breadboard
Software Used
- Arduino IDE
- Processing 3
How It’s Made
I connected the ultrasonic sensor and Arduino Nano and the servo motor. Then I attached the sensor on the top head of servo, so that it can rotate. Then, I uploaded the program.
For more info watch my YouTube video.
