Controlling a robot with your hand gestures feels futuristic — and in this project, we’ll make it real using Arduino Nano, MPU6050, and HC-12 wireless modules. You’ll wear a glove with an MPU6050 sensor that detects hand movements and sends commands wirelessly via HC-12 to control the car.

A wireless RC car that moves:

• Forward when your hand tilts forward
• Backward when your hand tilts back
• Left/Right when your hand tilts left/right
• Stops when your hand is level

Components Require:

Receiver Side:

How its Work :

MPU6050 detects the orientation of your hand.

Arduino Nano (Transmitter) reads sensor data and sends a command (F/B/L/R/S) via HC-12.

Arduino Nano (Receiver) receives the command via HC-12 and drives the motors using L298N.

MPU6050 Pinout:

HC-12 to Nano:

Code——Transmitter Side:include

#include<Wire.h>

#include<MPU6050.h>#

#include<SoftwareSerial.h>

MPU6050 mpu;
SoftwareSerial HC12(3, 4); // RX, TX

char command;

void setup() {
Serial.begin(9600);
HC12.begin(9600);

Wire.begin();
mpu.initialize();

if (!mpu.testConnection()) {
Serial.println(“MPU6050 connection failed!”);
while (1);
}
Serial.println(“MPU6050 ready.”);
}

void loop() {
int16_t ax, ay, az;
mpu.getAcceleration(&ax, &ay, &az);

if (ay > 10000) {
command = ‘F’; // Forward
} else if (ay < -10000) { command = ‘B’; // Backward } else if (ax > 8000) {
command = ‘L’; // Left
} else if (ax < -8000) {
command = ‘R’; // Right
} else {
command = ‘S’; // Stop
}

HC12.write(command);
Serial.println(command); // Debug
delay(100);
}

Receiver Side Code

Receiver Side : Arduino Nano + HC-12 + L298N

Receiver Coding:

#include<SoftwareSerial.h>

SoftwareSerial HC12(3, 4); // RX, TX
char command;

void setup() {
Serial.begin(9600);
HC12.begin(9600);

pinMode(5, OUTPUT); // IN1
pinMode(6, OUTPUT); // IN2
pinMode(9, OUTPUT); // IN3
pinMode(10, OUTPUT); // IN4

stopMotors();
}

void loop() {
if (HC12.available()) {
command = HC12.read();
Serial.println(command); // Debug

switch (command) {
  case 'F': moveForward(); break;
  case 'B': moveBackward(); break;
  case 'L': turnLeft(); break;
  case 'R': turnRight(); break;
  case 'S': stopMotors(); break;
}

}
}

void moveForward() {
digitalWrite(5, HIGH);
digitalWrite(6, LOW);
digitalWrite(9, HIGH);
digitalWrite(10, LOW);
}

void moveBackward() {
digitalWrite(5, LOW);
digitalWrite(6, HIGH);
digitalWrite(9, LOW);
digitalWrite(10, HIGH);
}

void turnLeft() {
digitalWrite(5, LOW);
digitalWrite(6, HIGH);
digitalWrite(9, HIGH);
digitalWrite(10, LOW);
}

void turnRight() {
digitalWrite(5, HIGH);
digitalWrite(6, LOW);
digitalWrite(9, LOW);
digitalWrite(10, HIGH);
}

void stopMotors() {
digitalWrite(5, LOW);
digitalWrite(6, LOW);
digitalWrite(9, LOW);
digitalWrite(10, LOW);
}

Power Supply

• Transmitter (Glove): 9V battery or LiPo with 5V regulator.
• Receiver (Car): 12V battery for motors and 5V regulator for Nano.

Testing

1. Upload both codes.
2. Power on both systems.
3. Wear the glove and move your hand:
   • Tilt forward → Car moves forward
   • Tilt backward → Car reverses
   • Tilt left/right → Car turns
   • Keep hand flat → Car stops
