Timers 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). User can set the …

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: • …
