L9110S H Bridge Stepper Motor Dual DC Driver Controller Module DocumentationOverviewThe L9110S H Bridge Stepper Motor Dual DC Driver Controller Module is a compact and versatile motor driver designed for controlling stepper motors and DC motors using microcontrollers like Arduino. This module features two L9110S H-bridge driver ICs, allowing it to drive two motors simultaneously.Pinout and ConnectionsThe module has the following pins:VCC: Connect to the positive terminal of the power supply (5V-12V DC)
GND: Connect to the negative terminal of the power supply
EN (Enable): Connect to a digital pin on the microcontroller to enable/disable the motor driver
IN1 and IN2: Connect to digital pins on the microcontroller to control motor 1
IN3 and IN4: Connect to digital pins on the microcontroller to control motor 2
M1A and M1B: Connect to the stepper motor or DC motor 1
M2A and M2B: Connect to the stepper motor or DC motor 2Arduino Code Examples### Example 1: Basic Stepper Motor ControlThis example demonstrates how to control a stepper motor using the L9110S module with Arduino.```cpp
const int stepPin = 2; // IN1
const int dirPin = 3; // IN2
const int enPin = 4; // ENvoid setup() {
pinMode(stepPin, OUTPUT);
pinMode(dirPin, OUTPUT);
pinMode(enPin, OUTPUT);
digitalWrite(enPin, HIGH); // Enable the motor driver
}void loop() {
digitalWrite(dirPin, HIGH); // Set direction
for (int i = 0; i < 100; i++) {
digitalWrite(stepPin, HIGH);
delay(1);
digitalWrite(stepPin, LOW);
delay(1);
}
digitalWrite(dirPin, LOW); // Set direction
for (int i = 0; i < 100; i++) {
digitalWrite(stepPin, HIGH);
delay(1);
digitalWrite(stepPin, LOW);
delay(1);
}
}
```### Example 2: Dual DC Motor ControlThis example demonstrates how to control two DC motors using the L9110S module with Arduino.```cpp
const int motor1Forward = 2; // IN1
const int motor1Backward = 3; // IN2
const int motor2Forward = 4; // IN3
const int motor2Backward = 5; // IN4void setup() {
pinMode(motor1Forward, OUTPUT);
pinMode(motor1Backward, OUTPUT);
pinMode(motor2Forward, OUTPUT);
pinMode(motor2Backward, OUTPUT);
}void loop() {
// Move motor 1 forward
digitalWrite(motor1Forward, HIGH);
digitalWrite(motor1Backward, LOW);
delay(2000);
// Move motor 1 backward
digitalWrite(motor1Forward, LOW);
digitalWrite(motor1Backward, HIGH);
delay(2000);
// Move motor 2 forward
digitalWrite(motor2Forward, HIGH);
digitalWrite(motor2Backward, LOW);
delay(2000);
// Move motor 2 backward
digitalWrite(motor2Forward, LOW);
digitalWrite(motor2Backward, HIGH);
delay(2000);
}
