Digital Clock using Seven Segment Display and ATMega16

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 display. Before going through this digital clock AVR project it is recommended to complete the tutorial on Interfacing a Seven Segment Display with the AVR Microcontroller. Note: Although this AVR project was designed around the ATMega16 the project could ...

Fully Customized Device On/Off Timer

Timers are used in many different applications for example in Industrial Applications, to switch ON or switch OFF any device or a machine load for a specific period of time. In the same way the timers are used in Domestic Appliances like in Air Conditioners, Microwave Ovens, Washing Machines, Food Processors etc. The applications for the timers could also be seen in Military Applications and Space Applicati ...

How to configure Watchdog Timers of AVR Microcontroller (ATmega16)

Some high end applications require multiple or critical calculations to be done by the microcontroller. This may lead to cases when the controller enters into wrong or infinite loops. As a result of this, the system either hangs up or gets crashed. The solution to overcome these situations is to automatically reset the system whenever such a situation arises. The Watchdog Timer is a hardware or software gen ...

A Moving Alarm Clock Using Atmega1284

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. The whole unit is mounted on a chassis with caterpillar-style wheels driven by two small DC ...

Persistance of Vision Clock Using Atmega644

The goal of our project was to create a persistence-of-vision (POV) analog clock using an LED display. The clock has a visual alarm system which lights up the entire display for two seconds if it reaches an alarm time. The current time and alarm times are preset into the clock before it begins to spin. Once the times are set, the clock spins up to a very stable speed, where small interferences will not disr ...

Seven day alarm Using Atmega644

Introduction The variability of a college student’s class and school work schedule gives way to an abnormal sleep/wake pattern that is not experienced any other age group. Few lucky students have the pleasure of having all their classes start at the same time every day. However, most students do not have this luxury. This requires that most students reset their alarm clocks every night in to adjust to each ...
