2 Bit u Stepper using microcontroller

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 micro steppers but they were all prohibitively expensive and had lots of electronics on a circuit board. Time to design m ...

Drive a Stepper Motor with an AVR Microprocessor using ATTiny2313 microcontroller

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 out if it's a unipolar or bipolar motor. Have a look at Jones on Steppers for som ...

Servo Controlled Labyrinth using Microcontroller ATmega32

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. Credits: - To CarlS www.instructables.com/id/Servo-Controlled-Marble-Maze/ for inspiration. - To the AVR freaks www.avrfreaks.net especially Dean (aka abcminiuser) for his excellent tutorials.

Stepper motor Driver Using AT2313 microcontroller

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 output for the driver is up to 30V so you can connect an stepper motor of up to 30V. With t ...

PC Steppermotor Driver Using AT2313 µ-controller

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 step mode Accepts commands via the serial port of your PC. Can be used with any OS that has a ...

Stepper motor Control with Atmega16

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 4x4 keypad is used for entering the speed and selecting the direction. Load the hex file into the chip, dont forget to select the internal oscillator at 10Mhz. Then switch o ...

DC Motor Speed Control using PWM

This project gives a speed control of DC motor through PWM method. The Dc motor is derived by the L298 driver IC. You can also control the direction of the motor. There are three buttons to control the motor. Also a bar graph Led display indicate the speed of the motor. An proteus simulation file is also available at the download so that you can check the code on your PC. Project from this Link   Basco ...
