12+ H Bridge Circuit Diagram. It would be nice if a motor could be attached directly to a chip that controlled the movement. As you see we have used two types of transistor.
Arduino DC Motor Control using L298N Motor Driver … from 4.bp.blogspot.com
Tow pnp transistors and two npn transistors. You can check these power. For npn transistor if we give +ve input to base it will turn on and if we give 0 input it will be turned off.
I also show you how to build a bidirectional motor speed controller.website.
12+ H Bridge Circuit Diagram. Compete circuit diagrams of h bridge are shown below. You can check these power. For npn transistor if we give +ve input to base it will turn on and if we give 0 input it will be turned off. Ir2101 motor driver circuit diagram.
