,
i want dc motor controlled through 8051.
Example: 12Vdc requiring say, 100mA ?
Do you hav a prj to control its speed or just stop and start it?
hi,
You should decide on the motor control you require .
Start/Stop is a simple medium power drive transistor, the transistor base being switched by a 8051 output, via a base resistor.
For Start/Stop and simple reversing a 'H-bridge' is normally used, controlled by ON/OFF Fwd/Rev signals from the 8051.
For the above and SPEED control a 'H-bridge' driven by the 8051 using PWM control signals..
Which is it.?
