I had written a simple instruction for stepper motor and downloaded it into PIC16F84 but now i got a problem on driving the stepper motor...a unipolar stepper...it require 24V and 500mA...how could i get this output for my motor??? need help...from newbie...
Have a look at , simply disconnect link J1, and connect 24V to the top of the four diodes. This presumes your motor is actually 24V 500mA, and you're not over driving it and require current limiting.
nice info...but as my PIC16F84 output 25mA from it's i/o ...a question is does it enought supply for base current for this BC337 transistor?? or i need to search for 1 that accept 25mA for the base??? I kinda lost here...thanxx...

so means i just change the resistor will do??anyway i got this transistor MPS2222...so think i can use it as well...is that ok??since the Vcb=50Vdc...i not so total understand bout datasheet..soli for that....
