Controlling DC Motors using AVR Microcontrollers

This tutorial provides step-by-step instructions on how to use an AVR microcontroller (in this example an ATTiny2313) to control two DC motors using L293 motor driver. While the microcontroller can act like a brain through software and control signals from its input/output pins, it lacks muscles. Muscles to the “brains” are provided by motors, actuators … Continue reading


Building beginner’s microcontroller development board using ATTiny2313

This tutorial will talk about how to build a development board for the Atmel ATTiny2313 series microcontroller using minimal components. The board will support ISP (In-system Programming) using any supported programmer (e.g. AVRISP) and can also be used as standalone board once the code is burned into it. Using similar concepts, you can build identical … Continue reading


Build 5V regulated power supply from 9V DC adapter

Many different devices require DC power and thus, need something called an I.T.E power supply. ITE stands for “Information Technology Equipment” (Learn more here ) I had an iPod speaker system that no longer works. It came with a 9V adapter. Most of us, hobby electronics guys know very well that a regulated 5V DC … Continue reading
