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 ...

Atmega Alarmclock & Thermohumidity meter

First, let me introduce you my project. I made an Alarm clock with extended functionality & thermometer and humiditymeter. Everything started when my friend (who used to bring me some old electronic rubbish and I used to check if there's not something useful) brought me some cashing register display similar like that. When I first see them I knew that I will made from it alarm clock. I'm programmer and ...

Clock/temperature LED display

This project is based on the timer/counter 0 example. It shows time, date and temparature on 7 segment displays. Instead of the LCD display the time is shown on a four digit 7 segment display with common cathode. The date and temparature is shown on a 7 segment LED display with comon anode. The ATMEGA328 is used to control the display, the ATMEGA8 can also be used. The circuit use 6 I/O pins from port B and ...

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 ...
