Hi!
Hello and greetings for all.
In my first post i want to ask (and see if i can to explain), this problem for me:
I've a PWM 0-12 v signal (500 ma) and want to control a solenoid actuator that has middle point.
I connect the positive terminal pwm at middle point, and if i connect the other negative terminal to the actuator end one, move to right, if i connect it other side move to left.
All is fine! but here is my problem how to control with unique potenciometer in order to obtain gradual control for center, right and left?
I make the control with a potenciometer but it not have the wattage necessary and is not the correct, i think i need a transistor drivers for potenciometer control. But i don't know.
I should be very thankfully is anyone can help me or link to some circuit application for it.
