study about this l293d drive it will be useful for the upcoming session to learn about how to operate motor using atmega 8535 micro-controller….
Features
The L293D is a popular motor driver IC that is usable from 6 to12V, at up to 1A total output current. By itself, the IC is somewhat diffcult to wire and use, but the Compact L293D Motor Driver makes it much more convenient to use.
Board Special Features
- Four motor direction indicator LEDS
- Schottky EMF-protection diodes
- Socket pin connectors for easy logic interfacing
- Enable pins are user accessible.
