DC motor converts electrical energy in the form of Direct Current into mechanical energy. In case of motor, the mechanical energy produced is in the form of rotational movement of the motor shaft. The direction of rotation of the shaft of the motor can be reversed by reversing the direction of Direct Current through the […]

Introduction This project uses an Arduino microprocessor and a MAX522 8 bit serial DAC to produce arbitrary low frequency oscillator (LFO) waveforms. These waveforms are useful for driving a tremolo/vibrato circuit in a guitar amplifier such as the Lil Tiger or the Hammonator 2RVT. This is a second generation version of this project, see the

Using PWM (Pulse Width Modulation) to control a device is a common practice in embedded systems; for example, you can use it to control the light intensity of a LED or control the speed of a DC motor. In this article, we will explain how to get a PWM from the AVR Atmega32 and we shalll
How to control DC motor speed using PWM on Atmega32 Read More »
Servo motors are a type of electromechanical actuators that do not rotate continuously like DC/AC or stepper motors, rather they used to position and hold some object. They are used where continuous rotation is not required so they are not used to drive wheels (unless a servo is modified). In contrast they are used where

The servo motor is widely used in model hobbyist such as airplane R/C model for moving the rudder, ailerons, elevators and acceleration control or in the car R/C model for steering and acceleration control. In this tutorial we will learn how to control the servo motor as well as the simple close loop control algorithm

This note provides basic implementation details and procedural information to design and assemble a stepper motor system. The controller discussed here is the ATmel mega8, an 8-bit microcontroller (MCU). The note consists of a general description and gives highlights of implementing a basic stepper motor system application. To amplify the application, the software was generated

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
