Similarly, L293D is a 16 pin IC that also works on the same as L298N but has a change in its package type. This IC provides pins for variable power supply which is used to drive motor, i.e., if we power ic by 5v and supply voltage by 12v then motor will run on 12v but the logic in ic will be controlled at 5 v.ĭue to heat generation at the time of driving motor to describe it a heat sink is attached to the icon module to provide efficient heat dissipation The internal schematic of IC is a bit complicated but as a whole, it uses a combination of 4, not gates along with 2-PNP and 2- NPN transistors in two sets to control two motors simultaneously. It comes in two packages Multiwatt-15 and powerSO20 which are for different purposes. L298N is a 15 pin ic whose pinout is attached below for further reference.
#L298n motor driver without arduino drivers
In this project, the main part is Arduino UNO which is the heart of the project and for movement control, we are using L298N and L293D motor drivers which are used due to their h-bride for motor driving also two signal wires for bi-direction movement. because Arduino only can give low current on 3.3-5v at each port. we must take an example to understand better if are using 4 motors in an RC car the Arduino can’t operate these all four motors.
The two we are going to use in very famous and widely available in the market are l298n motor driver and l293d and both are necessary for control dc motor with Arduino? the motor driver which is compatible with BO geared motors and various other small ones. Motor drivers and motors come with various rpm and power ratings so choose them wisely for better compatibility. The driver for the motor is necessary as to drive the motor with its maximum power we have to send a signal to the driver and this can be done with the help of an l298n motor driver.
Controlling the motion of any device or any locomotive is a very complicated and big task especially when it is for automation Today we’ll tell you how you can control a motor using Arduino and a motor driver.
