Good Day All.
I would like some help and advice.
I have been building my own stepper motor controller.
The controller works fine by it's self, but now I would like to add some LED's to it, so that I can see the input pulses.
As my controller gets all its signals from my computers LPT port it's all 0-5v logic.
I have 3 LED's I want to add to my controller, Enable, Step, & Dir.
The Enable and Dir pin are not pulsed quickly so I get the full brightness of the LED's
But the step pin is pulsed very quickly, so the LED works but is so dim you can hardly see it.
Is there anyway I can get the LED to pulse at its full brightness.
Heres how I have got the LED's wired atm.
