DC motor driver (using L293D)


In this article, i will tell about running motor with help of L293D IC. Before we start, lets have a recall about H Bridge. An H bridge is an electronic circuit that enables a voltage to be applied across a load in either direction. These circuits are often used in robotics and other applications to allow DC motors to run forwards and backwards.

Security System


Security system can also be termed as proper access controll in the field of Information technology. Access control is the selective restriction of access to a place or other resources. The act of accessing may mean consuming, entering, or using. Permission to access a resource is called authorization.
