Interfacing DC Motor with Atmega32 Microcontroller

In some of your electronic projects you may want to control a DC Motor with Atmega32 Microcontroller. We can’t connect a DC Motor directly to a microcontroller due to following reasons. A microcontroller can’t supply the current required for the working of DC Motor. ATmega32 Microcontroller can source or sink currents up to 40mA but a DC Motor needs […]

A simple brushless sensorless motor driver for AVR Atmega

Brushless electric motor (BLDC motors) are synchronous motors that are powered by a DC electric source via an integrated inverter/switching power supply, which produces an AC electric signal to drive the motor. For an introduction to BLDC motors, please look at my sensored motor driver post, here: http://davidegironi.blogspot.it/2013/09/a-simple-brushless-sensored-motor.html For this project, I’ve implemented a simple brushless sensoreless

Drive a stepper motor with acceleration and deceleration using an Allegro driver on ATmega8

The stepper motor is an electromagnetic device that converts digital pulses into mechanical shaft rotation.Most common types of stepper motor can be bipolar or unipolar, depending on the winding. To make a stepper motor move, motor windings must be loaded in the correct order. A stepper motor move at steps, it’s accuracy is usually expressed

A simple brushless sensored motor driver for AVR Atmega

Brushless electric motor (BLDC motors) are synchronous motors that are powered by a DC electric source via an integrated inverter/switching power supply, which produces an AC electric signal to drive the motor. Additional electronics control the inverter output amplitude and waveform (and therefore percent of DC bus usage/efficiency) and frequency (i.e. rotor speed). Because the

PWM Motor Driver with MOSFET H-Bridge and AVR ATmega8

Here is a very simple project of controlling a small DC-motor (taken from an old personal cassette player) with ATmega8. The ATmega8 is having three PWM channels, out of which two are used here. PWM waveforms are fed to MOSFET (RFD3055) H-bridge. Here, direction is controlled using a two-position toggle switch and speed of the
