Arduino Ultrasonic Sensor :
For my assignment i attempted to use the ultrasonic sensor in my arduino kit accompanied by three 330 ohm resistors, eight jumper wires and three LED’s yellow, green, and red. Each color corresponds/lights up to how far my hand is away from the ultrasonic sensor, yellow being ‘close’ , green being ‘too close’ , and red being ‘the maximum’ distance.
For improvements:
I would like to add a buzzer that initiates a buzzing sound according to how close an object is to the ultrasonic sensor.
