Principle of Work: 

The Motor Driver Module 2Ch 1.2A 15V TB6612FNG works based on the H-bridge circuit configuration, which enables control of the direction and speed of DC motors. The module uses the TB6612FNG motor driver IC, which is a dual-channel H-bridge driver. The H-bridge is a configuration of four transistors that allows the motor to be driven in either direction by reversing the polarity of the applied voltage. To control the direction and speed of the motor, the module receives input signals from a microcontroller or single-board computer. The input signals include two PWM signals that control the speed of each motor, two direction signals that control the direction of each motor, and two enable signals that enable or disable each motor. When a PWM signal is applied to the motor driver module, the TB6612FNG IC regulates the voltage and current supplied to the motor to control its speed. Similarly, when a direction signal is applied, the module controls the polarity of the voltage supplied to the motor, allowing it to move in either direction. The enable signal allows the module to turn the motor on or off, conserving power when the motor is not in use. The TB6612FNG IC also includes built-in protection features such as overcurrent protection and thermal shutdown, which ensure the safe and efficient operation of the module and the motor. Overall, the Motor Driver Module 2Ch 1.2A 15V TB6612FNG provides precise control of two DC motors and is a reliable and efficient solution for various robotics, automation, and other projects that require precise motor control.

Library:

No library Needed

         

Code: 

The code controls two motors (Motor A and Motor B) using an H-bridge motor driver connected to the Arduino:

const int STBY = 10; //standby pin

//Motor A
const int PWMA = 3; //Speed control pin 
const int AIN1 = 9; //Direction pin
const int AIN2 = 8; //Direction pin

//Motor B
const int PWMB = 5; //Speed control pin
const int BIN1 = 11; //Direction pin
const int BIN2 = 12; //Direction pin

void setup() {
  pinMode(STBY, OUTPUT);

  pinMode(PWMA, OUTPUT);
  pinMode(AIN1, OUTPUT);
  pinMode(AIN2, OUTPUT);

  pinMode(PWMB, OUTPUT);
  pinMode(BIN1, OUTPUT);
  pinMode(BIN2, OUTPUT);

  stop(); //initially stop the motors
}

void loop() {
  move(PWMA, AIN1, AIN2, 255, 1); //motor A, full speed, left
  move(PWMB, BIN1, BIN2, 255, 1); //motor B, full speed, left

  delay(1000); //go for 1 second
  stop(); //stop
  delay(250); //hold for 250ms until move again

  move(PWMA, AIN1, AIN2, 128, 0); //motor A, half speed, right
  move(PWMB, BIN1, BIN2, 128, 0); //motor B, half speed, right

  delay(1000);
  stop();
  delay(250);
}

void move(int speedPin, int inPin1, int inPin2, int speed, int direction) {
  //Move specific motor at speed and direction
  //speedPin: pin for speed control
  //inPin1: pin for direction control
  //inPin2: pin for direction control
  //speed: 0 is off, and 255 is full speed
  //direction: 0 clockwise, 1 counter-clockwise

  digitalWrite(STBY, HIGH); //disable standby

  boolean inPinA = LOW;
  boolean inPinB = HIGH;

  if(direction == 1) {
    inPinA = HIGH;
    inPinB = LOW;
  }

  digitalWrite(inPin1, inPinA);
  digitalWrite(inPin2, inPinB);
  analogWrite(speedPin, speed);
}

void stop() {
  //enable standby
  digitalWrite(STBY, LOW); 
}

• In the setup() function, the code sets all the pins as output pins.
• In the loop() function, the code calls the move() function twice to move each motor. The first call to move() sets both motors to full speed and move them to the left. After one second, the stop() function is called to stop the motors, and then the code waits for 250 milliseconds. The second call  move() sets both motors to half speed and moves them to the right. After another second, the stop() function is called to stop the motors, and the code waits for 250 milliseconds again.
• The move() function takes three arguments: motor, speed, and direction. The motor the argument specifies which motor to move (Motor A or Motor B). The speed argument sets the speed of the motor (0 to 255, with 0 being off and 255 being full speed). The direction argument sets the direction of the motor (0 for clockwise and 1 for counter-clockwise). The function sets the STBY pin to high to enable the motor driver and then sets the AIN1, AIN2, BIN1, or BIN2 pins depending on which motor is being moved and the direction. Finally, the function sets the PWMA or PWMB pin to the specified speed using analogWrite().
• The stop() function simply sets the STBY pin to low to disable the motor driver, which stops both motors.

Comparisons:

The DRV8833 and the TB6612FNG are both dual H-bridge motor driver modules that are commonly used in robotics and other applications that require motor control. However, there are some differences between the two modules:

2. Current capacity: The TB6612FNG has a higher current capacity than the DRV8833, making it better suited for driving larger motors.
3. Control interface: Both modules use PWM signals to control the motor speed, but the TB6612FNG offers additional control modes such as "standby mode" and "sleep mode."
4. Heat dissipation: The DRV8833 has a smaller package size and lower power consumption, resulting in less heat generation than the TB6612FNG.
