Alarm Clock using ATmega32 Microcontroller

In this project we are going to design a simple Alarm clock using ATMEGA32 timers. ATmega32A microcontroller has a 16 bit timer, and we will be using that timer to count the seconds and develop a digital clock. [caption id="attachment_34830" align="aligncenter" width="650"] AVR Microcontroller Based Digital Alarm Clock[/caption] All the digital clocks have a crystal inside of them which is the heart of cloc ...

Alarm clock Using Atmega-328 and RTC

Hi everyone! This is my first instructable! After reading hundreds of instructables, I decided to make one myself. Clock is one of the most essential house hold things. There are various types of clocks like good old Pendulum clocks, Analog clocks and the now trending modern Digital clocks. Digital clocks has many advantages over the analog clocks like the Accuracy in time, easy reading of time when compare ...

DS3231 OLED alarm clock with 2-button menu setting and temperature display

UPDATE: I added an alarm function to both versions of the clock. UPDATE: I updated the code so that setting the clock does not affect the seconds accuracy - no resyncing of seconds required. UPDATE: I removed the personal messages from the clock code for the "Pusheen" version in the download links Video at:: http://youtu.be/ikNw1iLE9vg Alarm demo video: http://youtu.be/jlZBCuQeswA This is an OLED alarm cloc ...

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 ...

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 ...

Retractable Alarm Clock (RAC) Using Atmel Mega32

1.1  Motivation: Alarm clocks are essential in almost everyones daily life.  For most of us, we start our day to the sweet noise of our alarms.  While some people wake up instantaneously to the first chirp of an alarm, some struggle everyday to get out of the bed. The Retractable Alarm Clock is the next generation alarm clock that combines both active alarm feature and penalty system that trains the users t ...
