Summary of Stepper motor driver
This project describes a unipolar stepper motor driver operating in full-step mode. The ATtiny2313 microcontroller generates control pulses, which are then amplified by the ULN2003 driver. The driver accepts 5V inputs and can handle outputs up to 30V, allowing the use of an external power supply to power stepper motors up to 30V. Two push buttons enable manual control of the motor’s direction (clockwise or counterclockwise), or it can be controlled via the microcontroller.
Parts used in the Unipolar Stepper Motor Driver:
- ATtiny2313 Microcontroller
- ULN2003 Driver
- Unipolar Stepper Motor
- Two Push Buttons
- External Power Supply (up to 30V)
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
Hardware
The hardware consist of the AT2313 microcontroller which drives the ULN2003 driver and two push buttons to control the direction.
