Make an Obstacle Avoiding Robot

Overview

This project is about obstacle avoiding robot in this robot it will calculate the distance from the obstacles and make it move forward, backward, right and left.

In this obstacle avoiding robot if the ultrasonic sensor senses any obstacle it will give input to the hobby generator and it will move accordingly. If the slide switch is OFF then the motor will not work.

Hardware required 

Arduino Uno R3

Jumper Wires

L293D

Hobby generator

Slide Switch

Ultrasonic Sensor

Arduino Code : const int trigPin=13; const int echoPin=12; int enableA=8; const int motorPin1=3; const int motorPin2=5; int enableB=9; const int motorPin3=4; const int motorPin4=2; const int slideSwitch=7; int duration; int distance; void setup() { pinMode(enableA,OUTPUT); pinMode(enableB,OUTPUT); pinMode(motorPin1,OUTPUT); pinMode(motorPin2,OUTPUT); pinMode(motorPin3,OUTPUT); pinMode(motorPin4,OUTPUT); pinMode(trigPin,OUTPUT); pinMode(echoPin,INPUT); pinMode(slideSwitch,INPUT_PULLUP); analogWrite(enableA, 200); analogWrite(enableB, 200); Serial.begin(9600); } void loop() { if(digitalRead(slideSwitch) == LOW){ findDistance(); if(distance<=10){ //The robot will stop for a while rightMotor(0); leftMotor(0); delay(200); //The robot will move backward rightMotor(-255); leftMotor(-255); delay(300); //The robot will turn towards the right rightMotor(255); leftMotor(-255); delay(200); } else{ //The robot will move forwards rightMotor(255); leftMotor(255); } } //Since the Slide Switch is off, the robot will not move else{ rightMotor(0); leftMotor(0); } } void rightMotor(int speed) { analogWrite(enableB,speed); if(speed>0){ digitalWrite(motorPin3,HIGH); digitalWrite(motorPin4,LOW); } else if(speed<0){ digitalWrite(motorPin3,LOW); digitalWrite(motorPin4,HIGH); } else{ digitalWrite(motorPin3,LOW); digitalWrite(motorPin4,LOW); } } void leftMotor(int speed) { analogWrite(enableA,speed); if(speed>0){ digitalWrite(motorPin1,HIGH); digitalWrite(motorPin2,LOW); } else if(speed<0){ digitalWrite(motorPin1,LOW); digitalWrite(motorPin2,HIGH); } else{ digitalWrite(motorPin1,LOW); digitalWrite(motorPin2,LOW); } } void findDistance(){ digitalWrite(trigPin,LOW); delayMicroseconds(2); digitalWrite(trigPin,HIGH); delayMicroseconds(10); duration=pulseIn(echoPin,HIGH); distance=duration*0.0345/2; Serial.println(distance); }

Precautions

Connections should be done properly.

Arduino is case Sensitive so code accordingly.

Give different and appropriate colours to the wires.

Nicole Dalager \\ Assignment 1 \\ Adafruit Circuit Playground

In my first attempts of programming the Adafruit Circuit Playground, listed below are the various input and output relationships...

1. Left button turns on the right built-in LEDs

2. Right button turns on the left built-in LEDs

3. Slideswitch turns on light sensor and a higher pitched sound goes off with bright light and low pitch noise are emitted with dark light

4. The accelerometer sensor takes changes data from slight X- axis changes to turn on and off certain LEDs

Video will be shown in a later post
