Tip 1

The connecting cables can be soldered directly, but with switches and potentiometers it is easier to connect crimp sockets to the cables first, plug them onto the pins and then solder them.

Tip 2

In order to protect the connection electrically and to make it mechanically more robust you can use shrink tubing (here in the pictures: transparent).

Test functions

Change constants

The Arduino program consists of two files

In "parameterset4clock1.h" you can set some constants with which you can adjust the behaviour of the displays, the DFPlayer and the minute buttons of the alarm time.

Wall mounting

Ideal mounting height: the user should stretch his arms slightly angled upwards in the supine position and lying on his usual cushion. This height is optimal for the underside, the control panel of the alarm clock. Attach the mounting plate to the wall using dowels and screws.

Cable duct, power supply and power bank

Power supply with mains failure protection

To route the USB cable downwards or sideways, you can optionally use a cable duct (DIY store).

Place power supply unit and Power Bank according to the room conditions and make sure that both remain free of dust and objects (duvets, soft toys, magazines, etc.) that could impede heat dissipation. Otherwise there is fire hazard!
