A White LED Night Light Design

Leave a Comment / AVR ATmega Projects, Home Automation Projects, LED Projects / Ibrar Ayyub

BUT FIRST AN IMPORTANT NOTE: This project uses lethal voltages. If you are not experienced in working with lethal voltages, read this project, but don’t build it. You only have one life, and AC power can take it from you very quickly, or leave you with terrible injuries. When working on high voltages, remember: •

An Isolated Adjustable Auto transformer using microcontroller

Leave a Comment / AVR ATmega Projects, Home Automation Projects / Ibrar Ayyub

This is a means of testing AC mains operated circuits at variable AC voltages, and it also provides isolation to allow safe measurements of that circuit. A fused isolation transformer and a variable auto transformer connected together in a grounded, fire safe box. What more could you ask? Find updates at www.projects.cappels.org Introduction

Relay Timer with ATmega8 AVR MCU

Leave a Comment / AVR ATmega Projects, Home Automation Projects / Ibrar Ayyub

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).

Tea Timer using ATTiny2313 microcontroller

Leave a Comment / AVR ATmega Projects, Home Automation Projects / Ibrar Ayyub

I usually drink a lot of tea, and sometimes the tea tastes a lot better than average, which means that most times I make tea I fail at least partially. The taste of the tea depends on a lot of variables: The make of the tea. I buy my tea at Simon Levelt and they
