The ATMega16 Seven Segment Digital Clock In this ATMega16 AVR project we will be designing and implementing a digital clock with the aid of a Atmel AVR ATMega16 microcontroller and Seven Segment Displays. As such before going through this digital clock AVR project it is recommended to complete the tutorial on Interfacing a Seven Segment […]

Servo motors are so called “closed feedback” systems. This means that motor comes with control circuit, which senses if motor mechanism is in desired location and if not it continuously corrects an error until motor reaches proper point. Servo motors are widely used in robotics, remote controlled planes, vehicles. So they come in many shapes

Sometimes in embedded design you may want to go wireless. Might be you will want to log various readings of remotely placed sensors, or simply build a remote control for robot or car alarm system. Radio communications between two AVR microcontrollers can be easy when specialized modules are used. Lets try to run very well

Hello and Welcome back to the second part of Obstacle Avoiding Robot Tutorial. In the last part we studied the drive system and the mechanical construction of our robot. In this part we will make the sensor part. The sensors will help our robot detect obstacle in its path. The sensor system is of very

One of the relatively unexplored topics in this week’s lecture was USB, the ubiquitous protocol that allows computers to communicate with peripheral devices (containing microcontrollers). Creating a USB device allows any computer to talk to it without the specialized software and hardware we’ve been using so far. For these two weeks, I decided to understand

Introduction Contents [show] In this tutorial, you’ll learn how to control a DC motor’s direction using an H-bridge. To reverse a DC motor, you need to be able to reverse the direction of the current in the motor. The easiest way to do this is using an H-bridge circuit. There are many different models and

For my final project I built a sous-vide immersion cooker: Sous-vide is a method for cooking food in a temperature-controlled water environment for longer than normal cooking times, at an accurately regulated temperature. Sous-vide cookers are often used in high-end restaurants. In the past few years, however, they have become more popular in household kitchens.

In this tutorial, we design an Arduino Uno Robotic Arm. Entire arm will be designed from some scrap material and servos. Entire process of construction has been explained in detail below. The arm has been built with cardboards and the individual parts have been locked to servo motors. Arduino Uno is programmed to control servo motors.

Blinking LED is the first step you would like to take to get started with electronics. In this tutorial we are going to connect an LED with ATmega32, which is an AVR series microcontroller. We are going to blink the LED at half a second rate. Components Required Hardware: ATmega32A Microcontroller Power supply (5v) AVR-ISP Programmer

To establish a good communication between human world and machine world, display units play an important role. And so they are an important part of embedded systems. Display units – big or small, work on the same basic principle. Besides complex display units like graphic displays and 3D dispays, one must know working with simple displays
