This is the second stepper motor driver circuit I build. The first one had 4 linear current sources and got so hot it was barely usable. It had some cool leds though. When I was searching for a better schematic on the internet I couldn’t find any to my linking. I did find some commercial […]

Got some scavenged stepper motors from printers/disk drives/etc lying around? Some probing with an ohmeter, followed by some simple driver code on your microprocessor and you’ll be stepping in style. Step 1 Get to Know Steppers Basically, you’re going to need to figure out where all the little wires go. First step is to figure

Do you know this classic wooden labyrinth game with two knobs for X and Y rotation? So, I’ve decided to modify one by connecting two standard servos to the knobs and let a microcontroller (ATmega32) play the game.

Description With this circuit you can drive a unipolar stepper motor. It operates in full step mode. You can get a stepper motor from an old 5.25 disk drive. 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

Description With this circuit you can control two unipolair stepper motors in full step mode via the RS232 serial port of your PC. A terminal program such as Hyperterminal can be used to control the stepper motors. The stepper motors can be driven one at a time. Features: Drives two unipolair stepper motors in full

With this project you can control a unipolar stepper motor. You can control both the speed and the direction of the motor. The speed and direction and can changed with help of the keypad. The data’s are displayed over the LCD display. A 4×4 keypad is used for entering the speed and selecting the direction.
