I have a PicBasic wich I programm it well. I want to do a Stepper Motor controler under 12Volts. I wish carry out It by Potentiometer. The power part it is clear, the motor seems turn good.
I have a standard varius resistor (pot.) of 100 Ohms.
How to Create an Out Voltage from 0-5V accuratly ?
Thanks.
Jerome,
What about a couple of NAND gates as wired up as a multi-vibrator?
Not sure how accurate is accurate but pots do not really have good resolution and are not easy to set to a precise value.

Pot. : because I'm currently controlling this dc motor by the potentiometer installed on the board Pic; and I don't understand this operate.
Multivibrator it's an great idea, but I have to thinks on.
Thanks.

If you just want a voltage to input to an ADC, use a higher value pot and connect it as a voltage divider across the supply, assuming that it is 5V. 10K is a good choice because the maximum source impedance is
2.5K, and it has reasonable power consumption.Best regards, Spehro Pefhany
