The project was designed as an AVR witch timer that can turn OFF lamps after a minute of exposure on a UV exposure box for PCB prototyping. The old good ATmega8 microcontroller was used in this ...

[Steven Mackaay] added a simple user interface that implements a shutoff timer for his desk lamp. His project log comes in two parts, the breadboarding and the actual implementation. He wanted a few ...

The objective of the circuit is to be able to provide a night lamp with an ultra low current consumption from a battery source in case of the absence of wall mains socket. TS555 – a single CMOS timer ...
