Hi,

This is my 13th instructable and in this tutorial, I'm going to show you, how to build a simple Gesture Controlled Robotic Car by using Arduino, accelerometer and RF modules.

Before getting started just hit the vote button because i need a new laptop for my projects i think you guyzz help me...

let's start with component we need

Step 1: Components and Software

Arduino Board
RF315/433 module
Wires, Pins
Accelerometer
L293d
Encoder and Decoder
Motors, Wheels & Caster Wheel
Glove
General purpose pcb, Soldering iron
Power source

Step 2: Circuit Diagram, Soldering, Connections

Make connection as mention below for the glove

For Gyroscope.

Connect "SDA" from your accelerometer to analog pin 4(A4) of the Arduino.
Connect "SCL" from your accelerometer to analog pin 5(A5) of the Arduino.
VCC to arduino 3.3v pin.
GND to arduino GND pin.

For Transmitter Module

Connect VCC to arduino 5v pin.
Connect GND to arduino GND pin.
Connect Rest of pins of ENCODER & TRANSMITTER as per the Figure 1.
At last connection for battery.

Make connection as mention in Figure 5. for the receiver(robotic car).

Step 3: Code

#include<wire.h>
const int MPU_addr=0x68;  // I2C address of the MPU-6050
int16_t X,Y,Z;
void setup()
{
  pinMode(10,OUTPUT);
  pinMode(11,OUTPUT);
  pinMode(12,OUTPUT);
  pinMode(13,OUTPUT);
  Wire.begin();
  Wire.beginTransmission(MPU_addr);
  Wire.write(0x6B);  // PWR_MGMT_1 register
  Wire.write(0);     // set to zero (wakes up the MPU-6050)
  Wire.endTransmission(true);
  Serial.begin(9600);
}

void loop()
{
  Wire.beginTransmission(MPU_addr);
  Wire.write(0x3B);  // starting with register 0x3B (ACCEL_XOUT_H)
  Wire.endTransmission(false);
  Wire.requestFrom(MPU_addr,14,true);  // request a total of 14 registers
 X=Wire.read()<<8|Wire.read();  // 0x3B (ACCEL_XOUT_H) & 0x3C (ACCEL_XOUT_L)    
 Y=Wire.read()<<8|Wire.read();  // 0x3D (ACCEL_YOUT_H) & 0x3E (ACCEL_YOUT_L)
 Z=Wire.read()<<8|Wire.read(); // 0x3F (ACCEL_ZOUT_H) & 0x40 (ACCEL_ZOUT_L)

  Serial.print("AcX = "); Serial.print(X);
  Serial.print(" | AcY = "); Serial.print(Y);
  Serial.print(" | AcZ = "); Serial.println(Z);

  delay(333);
  if(X > 3000 && X < 7000 )
  {
    digitalWrite(10,LOW);
    digitalWrite(11,HIGH);
    digitalWrite(12,LOW);
    digitalWrite(13,HIGH);
    }
 else if(X < -3000 && X > -7000 )
  {
    digitalWrite(12,HIGH);
    digitalWrite(13,LOW);
    digitalWrite(10,HIGH);
    digitalWrite(11,LOW);
    }
else if(Y < -3000 && Y > -7000 )
  {
    digitalWrite(12,LOW);
    digitalWrite(13,HIGH);
    digitalWrite(10,HIGH);
    digitalWrite(11,LOW);
    }
    else if(Y > 3000 && Y < 7000 )
  {
    digitalWrite(12,HIGH);
    digitalWrite(13,LOW);
    digitalWrite(11,HIGH);
    digitalWrite(10,LOW);
    }
  
    else
    {
      digitalWrite(10,LOW);
      digitalWrite(11,LOW);
      digitalWrite(12,LOW);
      digitalWrite(13,LOW);
      }   
}
