L298N Motor DriverΒ
l298N motor driver
L298N motor driver board module; It can directly drive two 3-30V DC motors and can also provide a 5V output interface. It can also provide 5V single-chip circuit to support 3.3VMCU control. With this card module, you can easily control DC motor speed and direction. In addition, it can be easily controlled by a 2-phase stepper motor used in smart vehicles. You can do it yourself by examining the 2WD robot car project using the L298N module.

How the l298N motor driver Board Works
H-Bridge is a modular circuit board that can drive a current in both polarities and can be controlled by pulse width modulation, that is, pwm, and is frequently used in projects.
Pulse Width Modulation is actually the determination of controlling the duration of an electronic pulse that occurs. If we imagine the brush in the motors as a rotating mill and the resulting current as water flowing on this mill; Let’s express the water flowing over the wheel at a constant rate as voltage. The more water flows, the higher the voltage will be. All of the motors used in the projects are scaled within a certain voltage range. In practice, the motor and circuit may be damaged if too much voltage is applied and/or if the value is rapidly reduced to slow the motor down suddenly. When we consider the pwm application as the analogy of the waterwheel in the mill. Increasing the voltage at certain rates and decreasing it at certain rates, just like the water transferred to the mill, will ensure that the motors used in the projects have a longer life. The longer the pulses, the faster the mill wheel rotates. The shorter the pulses, the slower the mill wheel rotates.
