Stepper motor driver using atmega

Stepper motor driver

With this circuit you can drive a unipolar stepper motor. It operates in full step mode. The AVR attiny2313 micro controller controls the pulses for the stepper motor. The pulses are amplified by the ULN2003 driver.

The driver accepts 5V inputs, the output for the driver is up to 30V so you can connect an stepper motor of up to 30V if you use an external power supply. With the two push switches you can drive the stepper motor CW or CC or control it with a microcontroller
