This two axis stepper motor control system uses attiny2313 microcontroller. And it utilities the l298 dual h bridge power ic in multiwatt 15 package. The code is easy to write. Dual power supply for the microcontroller and l298 allows for increased isolation. The circuit must use a transformer for the proper galvanic isolation. This is a crude circuit as it needs some filter capacitors to reduce the voltage and current spikes.
