DC Servomotor Controller System Meter using ATtiny2313 microcontroller

The ATtiny2313-based project is an experiment on the closed loop DC servomotor control system (SMC) by Elm Chan. It can be used for practical use with/without some modifications. The closed loop servo mechanism requires real-time servo operations, such as position control, velocity control and torque control. It will be suitable for implementation to any embedded 32 bit RISC processors as a middleware. To c ...

Electric Spinning Wheel using ATmega8 microcontroller

The Electric Eel Wheel is a smart electric spinning wheel which helps you spinning the fiber of your choice into yarn easily instead of traditional wheel. This Electric spinner is lighter and smaller, making it easier to take your spinning with you. You can control spinning speed and its direction, forward or reverse. The electronics part of the project consist of DC motor, IC L298 (motor driver) and ATmega ...

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. Ple ...

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 ...
