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. ![]() ![]() 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.
