Hi everyone,
I am in need of some advice on how to design a circuit to control a 12VDC motor with the use of PWM from a microcontroller.
Basically I have a Philips (now NXP) LPC2129 and a 12VDC motor. What kind of circuitry do I need from my microcontrollers PWM output that will allow me to supply 12VDC and the necessary current to my motor?
Would I use a high power transistor with a low base switching voltage?
If anyone has any kind of circuit diagram for achieving this, or even a link to a diagram I would be most grateful.
Thank you for your time,
Rob
