how to perform a control board of a stepping motor

Here is a motor control card stepper based 16F877A PIC circuit I have designed and built.

The aim of this project had $ r'ealiser a motor control card not `none

small dimensions. This allows pi`ece as the name suggests, on /'eteindre a

small engine not `none, to change its direction of rotation but'egalement r'egler of the report

cycle engine operation is `is the ratio between the time the engine is o`u

`to the stop and that he makes a o`u not (here it is no 7.5˚). For simplicity one can

say that it is possible to vary the motor speed. So we can say that one of the

project objectives'et'e to become familiar with the'electronique and some components

quite common that we had not had the opportunity to manipulate far for most

of us.
