This tutorial shows you how to decode SONY Remote Control using microcontroller AVR. The project use external interrupt at the falling edge to detect the pulse. The project use AT MEGA 16 and vcd remote control sensor or you can use any type sensor that have filter of 38 KHz to 40 KHz on it. […]
People still use 16-key keypad as input device for any embedded project. I could be used as code input device for opening a door or as a general input to any project that requiring the input like alarm circuits, games, puzzles, DTMF generators. This project will show you how to interface a 16-key keypad to […]
In this video tutorial, nerdkits show you how to use the timer interrupts on an ATMega168 chip to make a simple timer. It is possible to make your own reasonably accurate alarm clock, create systems to perform timed automated tasks, or create a multitude of other projects with real time clock in AVR.
We know that most flashlights require three cells because they are regulating output current with only series resister. The odd number of cells except one is not good, and a margin between VLED and VBAT is too small, intensity of light is affected by variation of input voltage within the battery life.
