Circuit Documentation

Summary

This circuit integrates an Arduino UNO microcontroller with two HC-SR04 Ultrasonic Sensors and two Coreless Vibration Motors. The Arduino UNO is used as the central processing unit to control the ultrasonic sensors for distance measurement and to drive the vibration motors based on sensor inputs.

Component List

Arduino UNO

  • Description: A microcontroller board based on the ATmega328P.
  • Pins Used: IOREF, Reset, 3.3V, 5V, GND, Vin, A0-A5, SCL, SDA, AREF, D0-D13.
  • Purpose: Acts as the central controller for the circuit, interfacing with sensors and motors.

HC-SR04 Ultrasonic Sensor (x2)

  • Description: An ultrasonic distance sensor capable of measuring distances from 2cm to 400cm.
  • Pins Used: VCC, TRIG, ECHO, GND.
  • Purpose: To measure the distance to objects in front of the sensor.

Coreless Vibration Motor (x2)

  • Description: A small motor that vibrates when electricity is applied.
  • Pins Used: positive, negative.
  • Purpose: To provide haptic feedback or alerts based on sensor inputs.
