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 …

Since iRobot hasn’t provided linux users with a way to use the command module, I had to figure it out myself. Don’t be intimidated, its not hard at all, really. All you need to do is run a couple of scripts. Lets get started, shall we? Step 1 Get the goods For this tutorial, I’m assuming you have …
In this tutorial we will discuss a simple PC controlled robot. The Robot PC link will be a RS232 serial line. The robot will have only five commands. Move forward (RS232 char ‘F’ or ‘f’) Move backward (RS232 char ‘B’ or ‘b’) Turn Left (RS232 char ‘L’ or ‘l’) Turn Right (RS232 char ‘R’ or …

A microcontroller is a device which has an inbuilt processor surrounded by few dedicated hardware modules. Once the microcontroller initializes them they start operating on their own. In case of an ADC it will do the sampling and digital to analog conversion all by itself and keep the converted data in its buffer so that …
AVR ATmega32 Mini Development Board is interfaced with a LCD module (2×16) operating at 5V. The voltage at the third pin of the LCD can be varied by potentiometer to adjust contrast. LCD can work either in 4 or 8 bit mode. Read More: AVR ATmega32 Mini Development Board – Interfacing LCD
This article is another step forward in learning more about AVR microcontrollers. We have demonstrated interfacing of LCD module with ATmega328 microcontroller, which will help you to learn its basic concepts. ATmega328 is an eight bit AVR (Advanced Virtual RISC) based microcontroller. It is a powerful microcontroller with a built-in internal memory of around 32Kb. Atmega …

Subject: Daily life activities of food preparation can be challenging for consumers due to restricted skills and experience, loss of perceptive abilities (accident/aging) or due to product fraud and contaminations, commonly summarized under the term of food adulteration, which are exceeding human perceptive abilities in general. Thus, in our work the E-Taster-assistance-system for living assistance …
Today we are here with an interesting project in which we will Send Data to the SparkFun server using Arduino and GPRS. This is an IoT based project in which we will use GPRS, present on the GSM Module SIM900A board, to send some data to the web service on the internet. In this project, we will simply enter …

This is a very interesting project in which we are going to learn how to implement virtual reality using Arduino and Processing. For most of us, the movie Iron man by Jon Favreau has always been an inspiration to build new things that will make our life easy and more fun. I have personally admired …
