Robot Car with mobile App
This is 15th project for the course of robotics and iot
This project is to learn how to drive robot car, Drone, Trolly, or any other vehicle with mobile App.In this project You will learn
1 How the motor drivers L298 works with the motors
In this total data pins are 4 , Enable pins are2, Power supply pin are 3 and left and right motor each have two point.
Motors pins are directly connected to Motors.
Enable and Data pins are connected to Arduino
These 6 pins are HIGH or LOW are decided by the program we have written for Arduino.
Through Power supply we give voltage of 8-46 volts depending upon the motors.
2 How to program the Arduino for driving any vehicle by mobile App. Each motor has two point one is +ve and the other is -ve.
One connection is +ve and other connection is –ve , if its moving in clockwise direction then reversing both points motor will move in anticlockwise direction.
For moving forward both motors should move in clockwise or forward direction
For moving Backward both motors should move in anticlockwise direction.
For moving left , only left motor should in forward direction.
For moving right only right motor should move in forward direction.
So keeping this in our mind we write the program and write pins level (H/L )as per our requirement.
For writing the program, 1 we will assign the pin numbers for INPUT AND OUTPUT 2 Initialize them 3 Write the status of 6 PINS of arduino as per requirement
