Let’s connect a motor to channel a and demonstrate the basics of direction control using the digital write command. So keep that in mind when selecting your microcontrollers both Arduino and Raspberry Pi will work fine for with this board. If you want to control speed and direction you will need to use pulse width modulation PWM pins a potential of atleast 2.5 volts is required for the control board to recognize a high signal. Now if you are only concerned about motor direction you can use regular digital high-low output pins. The pins are either labeled 1a or 1b we will discuss that more in a minute these are the pins that need to be connected to the Arduino. The two pins on the right are for controlling motor A and the two pins on the left are for controlling motor B. The onboard LED indicates when the board has power, I do not recommend connecting ground and VCC to your Arduino as this can overload the power supply depending on the power required to drive the motors. To the right is the VCC pin which should be connected to the positive terminal of your power supply. Now let’s talk about the pin headers, the third pin from the left is the ground pin and should be connected to the negative terminal of your power supply.
The L9110 Motor Driver can be used to control two small DC motors simultaneously or can be used to control a small stepper motor. The L9110 Motor Driver is a compact and inexpensive h-bridge motor control board that easily interfaces with microcontroller boards such as the Arduino, Raspberry Pi, ESP32, STM32, Nodemcu ESP8266, etc.
In this tutorial I will show you how to use the L9110 motor driver board and write simple Arduino code to control various types of motors in your own personal projects. The board can be operated from 2.5V to 12V enabling this module to be used with both 3.3V and 5V microcontrollers.
This module has two independent motor driver chips which can each drive up 800mA of continuous current.
