i use PIC16f84A to control a DC motor directly .........but it does not work.....i dont know why ???????????????
when i'm use a varilable supply, DC motor work at 0.7 volt
can any body solve this problem to me........
u'll need an H-bridge , or atleast a power transistor (eg-3055) to drive a motorsaloom said:can somebody helpme in this problem

But my main problem that i have 8-10 DC motors so haw can control them seperatly...............
if i want to use a H-bridge, ineed 4-transistors for each motor.
so 4 by 8 motors = 32 transitors.....................
it's impossible to use it in small area
DigiTan said:I've got a similar question. For controlling multiple motors, that is.
Is there any kind of PWM control IC that will -say- take a digital input and latch the pulse width? That way it would continue its PWM until the next digital input arrived? It seems excessive to have a seperate µcontroller generating PWM for each motor.
saloom said:thanx for you.......................but still i have one question..
i saw many robots like 'robosapien' and i check it's internal structure.i'm noy found any tibe of H-bridge..........i'm amazing that they are conect microprocessor directly to the motor................
any body can answer my quetion????????????????????????
