This is my first idea for Arduino, and below I will tell you how this tool works. In this tutorial I will show you how to detect objects when we drive a car.Step 1: Component and Setup
- One breadboard
- Speaker buzzer
- Motor DC
- Sensor passive infrared (PIR)
Sensors installed in the car will detect moving objects. This tool will only detect moving objects, that is, humans.
When the car was oncoming at a speed that fast, and then at the front there is a man who was crossing the street, the sensor will automatically detect the object and the sensor will send a signal through the module Bluetooth HC-05 in the form of sound installed in the car, then motorists will reduce the speed of the car. The sensors capture the distance reaches 100 to 300 meters.
