In this tutorial we will make a “Digital Stop Watch” using an AVR ATmega8 Microcontroller. This will help you learn many concepts like Multiplexed Seven Segment Display Interfacing Using AVR Timers Using Interrupts And many others too. The code is written in C language for avr-gcc (WinAVR) . Steps to Build the “Digital Stop Watch”

Timer are widely used in industrial and domestic application for automating tasks. Microcontrollers can be used to design versatile and accurate timers with ease. Here I present a simple timer that can be used to turn on/off a load after user specified time. The Timer uses a standard 16×2 lcd module for user interface (UI).

ADC (Analog to digital converter) is a commonly used peripheral. We use it everyday to interface with several analog sensors. Many times a nice visualization of ADC data is required during learning about new sensors. For example you just bought a analog sound sensor, and try to do some fast experiments that how it performs.
