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

Similar to printing ‘Hello World’ in C or C++, the very first step towards programming a microcontroller is Blinking a LED with a delay. Atmega32 is a very popular high performance 8 bit AVR Microcontroller. For this example project we need to use two registers DDR and PORT. DDR stands for Data Direction Register, it

Recently I was working on a project that involved rotary encoder. I thought I’d share some thoughts on how rotary encoder can be interfaced and programmed. Actually it is easy to work with rotary encoders – interfacing is simple – only three wires are required to connect to microcontroller (two for signal (quadrature outputs) and

INTRODUCTION: A lot of electricity is wasted due to ignorance or fault of the user. Sometimes a person in the room turns on all the electric equipments which is of no use to them. As an example, supposedly a person enters in the hall or conference hall (where a large number of tube lights or fans
Microcontrollers are capable of detecting binary signals: is the button pressed or not? These are digital signals. When a microcontroller is powered from five volt, it understands zero volts (0V) as a binary 0 and five volts (5V) as a binary 1. But the real world is not so simple and likes to use shades
