Hey hello, I am new in electrical system design. I almost know nothing. I need your help. And I have to control a DC motor's speed. My DC motor is 6V and I am not going to use a PIC. Is it possible or not I thought it was possible but as I said I know nothing. I thought of buying a NTC thermistor and connecting it into the system so if tempreture is high, resistance is going to be lower than it was. And my DC motor will gain more speed. But I searched almost all the internet I couldnt find a proper answer about connecting it into the ststem. I tryed to connect it serially with my DC motor but it doesnt really work. I saw some parallel connected system designs they got a resistor and a thermistor parallel connected. If you can help me I would be soo happy :) Thanks.
