Project description:
Offering remote earnings for the developer of electronic devices. You need a working scheme and a ready-made device (its video presentation). The price of the issue is ready to be discussed separately.

The circles in the picture are LEDs. They should be lit in turn at intervals of N minutes. You need a switch off button, and if possible, a pause button for the timer.

There is also a desire to have an audio signal for 3-5 seconds when switched on. (optional)

The timer control device is not oversized.
