Please could anyone help me ! I need to build my own driver board to drive unipolar steppers (surplus printer steppers)
I`m not looking for anything fancy i just want to make a start
So far i have collected numerous ic`s ULN28003, ULN2003,74LS74,74LS86,L293D,TIP120 various resistors, capasitors etc. but i can only find minimal info on the web.
