Make yourself a homemade clock with thermometer using ATMEGA128

In this step by step I wanna share my experiment with ATMEGA128 timer and interrupt using DS1307 and NTC to display homemade clock and thermometer. It displays hour,minute,second, day of week, day of month, month, and year, and the temperature in celcius Enjoy the project... Step 1: Prepare all the parts for this project This project will need these parts : 1. ATMEGA128 board 2. ATMEGA 128 chip 3. DS1307 mo ...

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 ...

A Wireless Programmable Pace Clock Using Atmega644

For our ECE 4760 final project, we designed and built a wirelessly programmable digital pace clock with a large format LED display and Android smartphone control and programming. This original design achieves the functionality of commercailly available pace clocks but with an intuitive user interface that goes beyond anything that is available in the current marketplace, all at a small fraction of the cost. ...

Adaptive Alarm Clock Using Atmega644

Introduction Elevator Pitch / 1-second Description An adaptive alarm clock that chooses the optimal time to wake up the user using an accelerometer that detects his/her body movements. Goals The goal of our final project was to create an alarm clock that is able to detect your sleep patterns and wake you up at the optimal time, i.e. when you are in the lighter phases of sleep. Our goals for this project wer ...

Alarm clock with speech synthesis Using Atmega32

1. Introduction We designed an intelligent alarm clock which can be programmed from the computer to speak custom messages and also detect whether the user is on his bed or leaving his room. Sensors are pervasive in industrial, aerospace, and medical fields. Although they can potentially enhance the common person's everyday-life, they are still seldom used in most consumer electronics. In line with future de ...
