To solve this problem the use of a motor driver is essential. Hence the output of Arduino is not enough to power up the motors. Also, the output current limit of Arduino is relatively very low. But a decent DC motor needs at least 5V or 12V. For instance, the Arduino or PIC microcontroller can output a maximum voltage of 5V or 3.3V. Why do we need a motor driver module?Īll microcontrollers operate on low-level voltage/current signals, unlike motors.

The IC alone can control the DC motor but using the module makes the interfacing with Arduino easy. The motor driver module consists of a motor driver IC, which is the heart of the module. To put it in simple words, you can control the direction of DC motors by giving appropriate logic to the motor driver module. This input logic controls the direction of DC motors connected to the driver. A motor driver module takes the low voltage input from a controller like Arduino. It is commonly used in autonomous robots and RC cars. The higher the duty cycle, the greater the average voltage being applied to the dc motor(High Speed) and the lower the duty cycle, the less the average voltage being applied to the dc motor(Low Speed)Ī motor driver module is a simple circuit used for controlling a DC motor. The average voltage is proportional to the width of the pulses known as Duty Cycle.

PWM is a technique where average value of the input voltage is adjusted by sending a series of ON-OFF pulses. A common technique for doing this is to use PWM (Pulse Width Modulation). The speed of a DC motor can be controlled by varying its input voltage.

Sample Code // # Editor : Lauren from DFRobot This tutorial shows you how to use l298N motor drive shield to drive two DC motors. Note: LOW = 0 HIGH = 1 PWM = 0~255 Tutorial M1 = 1,the motor rotates in back direction. Eg: M1 = 0,the motor rotates in forward direction. If motor power supply is more than 12V, dont't short jumper! Motor Control Pins If motor power supply is less than 12V,you can set jumper shorted. When jumper is shorted, logic power supply voltage is the same as the motor power supply. GND: The common ground of Logic Power Supply and Motor Supply.Motor Status LED: Motors work normally, thus the lED will light up.The terminals are used to connected to the motors, which labeled "+" and "-" representing motor polarity. Drive Type: Dual high-power H-bridge driver.Operating temperature: -25 degree Celsius ~ +130 degree Celsius.Maximum power dissipation: 25W (T = 75 degree Celsius).Drive part of the operating current Io: 2A.The logical part of the work current Iss: 36mA.Driven part of the input voltage Vs: 4.8 ~ 46V.The logic part of the input voltage: 6 ~ 12V.The driver uses a broad-brush design to reduce wire resistance. This chip allows for direct drive of two bi-directional DC motors, and incorporates high-speed short diodes for protection. It is easy to control, using LGS's outstanding high-power motor driver chip, the L298N. It can bear larger current due to the increased haetsink dissipation. Its performance has been improved greatly. This is a 4.8-46V, 2A Dual Motor Controller which is the revised version of the DF-MDV1.0.
