In this tutorial, I will walk through interfacing a push button with the Atmega16 microcontroller. It is assumed the reader has some familiarity with basic microcontroller concepts from my previous post on blinking an LED. Before connecting a push button, we must understand how to configure ports for input and output. Ports need to be […]

During this week’s lecture, we delved into a relatively less-explored subject: USB, a widely-used protocol enabling computers to interact with peripheral devices equipped with microcontrollers. Developing a USB device empowers any computer to establish communication without the need for the specialized software and hardware that have been our focus thus far. For the next two

This tutorial will provide an understanding of push buttons and their integration with the AVR ATmega32 microcontroller. While push buttons can be applied to control various devices, we will focus on using them to manipulate an LED in this demonstration. Additionally, we will delve into the utilization of “if and else” statements in the C

In the previous article, I discussed the USART module of the ATMega32 device, providing some practical examples. In this article, I will present additional USART examples that involve AVR C programming techniques. These techniques include creating conditions based on received characters and utilizing the ANSI C string functions library. In this straightforward illustration, the user

Introduction Atmel, AVR microcontrollers (MCUs) are very easy to use. All AVR microcontrollers require Integrated Development Environment(IDE) such as Atmel Studio. Using this IDE, we can create, compile, and debug programs on all AVR microcontrollers. Atmel Studio is available free of charge. To download and install the latest Atmel studio use this link. Note: There are possibly

One of the interesting projects for most of the embedded beginners enthusiasts or hobbyists is to build the LED chasing effect. In this project we are going to use both the Arduino IDE and Atmel AVR Studio to program the AVR ATMega168 microcontroller, therefore you could learn to use these well known Integrated Development Environment

There are inexpensive solar garden/walkway lamps available at most home goods and hardware stores. But as the old saying goes, you usually get what you pay for. The usual charging and illumination circuits they use are simple and cheap, but the light output you get is anything but impressive (and barely enough for anyone using

Introduction We implemented a prototype for a moving alarm clock which runs away from the user when they try to silence the alarm. It has all the features of a “regular” alarm clock: settable time and alarm, snooze, and alarm on/off. The alarm clock displays the time in 24-hour format on a LED seven-segment display.
