Hi everone,
I have made a DC motor speed control with 4093 IC. but it doesnt work correctly. I use a 12V voltage as its supply, but when I change the value of the variable resistor, output voltage isnt beed changed. and so the speed of motor is the same.
I better say that the output voltage is always the same of supply..
I have inserted the schematic of circuit here..
whats the problem ?
thank you
Eric
