Arduino RC Car With Tinker CAD

Hi guys, this is a instructable to learn a simple arduino rc car with very cheap and readily available materials.Check out the design.The base of the car can be done with either cardboard or chassis.Check out the supplies needed and get them ready.

*Arduino UNO

*Dc motars-2

*Breadboad(Medium sized)

*IR sensor

*LED(Any colour)

*H-Bridge Motar Driver

*Resistor

*IR Remote

*Jumper wires for connecting

*A to B arduino cable for programming.

Pc or Laptop for programming

Look at the image and assemble your components.

Connect your Arduino to pc or laptop with the help of Arduino A to B cable.Look at the code below copy and paste them in Arduino IDE app and upload it.

Code:

#include

const int PWM_M1 = 5;

const int IN1_M1 = 2;

const int IN2_M1 = 3;

const int PWM_M2 = 6;

const int IN1_M2 = 8;

const int IN2_M2 = 9;

int speed = 100;
