How to Make Drift Car Using Arduino

Hi everybody. Let me introduce about how i made a DRIFT CAR using arduino, pololu VNH5019, NRC-20 control system and wrecked body of RC car.

Step 1: This DRIFT CAR Contains...

1. Arduino UNO R3 programmable board

2. Pololu Dual VNH5019 Motor Driver Shield for Arduino - https://www.pololu.com/product/2507

3. NRC-20 wireless control system

4. Li-Po battery 11.1V 2200mAh 35C 3S1P

5. Wrecked RC car with servo based on potentiometer and dc motor

Step 2: Connections

These will be connected leading to the picture

Step 3: Arduino Code

Download libraries and codes from github:

Main code: https://github.com/BTeTapxu/Drift-car-code-arduino

Download library: https://github.com/pololu/dual-vnh5019-motor-shield

CODE:

#include "DualVNH5019MotorShield.h"

DualVNH5019MotorShield motor;

unsigned char serial_in[7]={};

int i=0;

int analogPin = 3; // potentiometer connected to analog pin 3 int val = 0, comp;

void setup(){

Serial.begin(19200);

motor.init();

}

void loop(){

motor_move();

servo();

Serial.println(comp); //debug

if (Serial.available() > 0) {

if (i==6){

i=0;

}

i++;

serial_in[i]=Serial.read();

}

}

void servo() {

if(comp<map(serial_in[4],208,48, 14, 6)){

motor.setM2Speed(100);

}

else if(comp>map(serial_in[4],208,48, 14, 6)){

motor.setM2Speed(100);

}

else{

motor.setM2Speed(0);

}

comp=analogRead(analogPin)/50;

}

void motor_move() {

if(serial_in[1]<127){

motor.setM1Speed(map(serial_in[1],127,50, 0, -400));

}

else if(serial_in[1]>129){

motor.setM1Speed(map(serial_in[1],129,210, 0, 400));

}

else{

motor.setM1Speed(0);

}

}
