I have removed a two stepper motors from ink-jet printer. Every each motor have 2 COILS (1+1) that mean they have only 4 wires. How can i control stepp motor with some easy available logic ICs.
This is the simplest driver for bipolar (4-wire) steppers. I used BD239C and TIP30 transistors and all resistors are 1K. It uses phase drive instead of step-dir signals.
