AVT5622 A + - countdown timer. PCB board and programmed layout

Description

The presented device is a countdown timer down. Due to the fact that the current value is presented on a large, readable LED display, it can act as an advertiser - announcing that "until the end was ...". It can count down the time, eg the end of the working day or the time allocated to the child to use the computer, or the time until the end of any promotion. The applications can be really many, especially since the time range counts down to 100 days.
