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 …
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. Load the hex file …
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 …

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 …

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. …

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 …

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 …

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 …

As explained in earlier article, Stepper motor is operated by energizing the stator coils in an ordered sequence. When the input sequence of signal is applied to the motor leads, it starts rotating in steps. AT89C51 microcontroller has a current rating of 50mA. It can neither source nor sink huge current. ULN2003 is high voltage and …
