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 […]

In this project we are going to use one of the features of ATmega32A to adjust the brightness of 1Watt LED. The method that is used to adjust the speed of  LED is PWM (Pulse Width Modulation). The method of PWM is explained here. Consider a simple circuit as shown in figure. Now if the […]

We all know that one of the places where power wastage happens most in homes and offices is at staircases. We usually turn on light at stairs and leave it in a hurry. In this project we are going to design a stair case lamp which works on battery and only turn on the lights only […]

Whenever we go to vote for elections we come to see electronic voting machines. In this project we are going to design and develop a simple voting machine by using ATmega32A microcontroller. Although we can use the controller to get more than 32 people voting machine, to keep everything simple we are going to make a voting […]

We know in offices, shopping malls and in many other places where only the person with authorization card is allowed to enter the room. These systems use RFID communication system. RFID is used in shopping malls to stop theft as the products are tagged with RFID chip and when a person leaves the building with the RFID […]

In this tutorial we are going to design a 0-99 counter by interfacing two seven segment displays to ATMEGA32A Microcontroller. Here we count events based on number of times button is pressed. Before moving ahead, let’s understand what is a seven segment display. A seven segment display got its name from the very fact that it has […]

In this project we are going to design a circuit for measuring temperature. This circuit is developed using “LM35”, a linear voltage sensor. Temperature is usually measured in “Centigrade” or “Faraheite”. “LM35” sensor provides output based on scale of centigrade. LM35 is three pin transistor like device. It has VCC, GND and OUTPUT. This sensor […]
