Flux Capacitor Alarm Clock

Here it is ! The flux capacitor from back to the Future (more square).

It's an alarm clock and once the alarm goes off, it randomly plays sounds from the BTTF soundtrack.

I provide everything to make it.

How to use:

• Setup/Stop button: Set the alarm time
• hour + minute button: activate or deactivate the alarm ("0" alarm off, "1" alarm on)

When the alarm is rigging

• hour or minute button: snooze 5 minutes (time can be modified in the code)
• Setup/Stop button: stop the alarm

Special feature

• hour + minute button then hold the hour button until the feature starts.

Enjoy !

Paint the following parts:

FLUX_CAPACITOR_BACK_COVER

FLUX_CAPACITOR_BOX

FLUX_CAPACITOR_COIL_1,2 and 3

FLUX_CAPACITOR_DISPLAY_FRAME

Just slide the led inside the part.

You have to put the "IN" toward the outside.

Solder the 3 RGB together (see wiring diagram).

You'll see that I've put numbers on the coals, the "1" will be on the up left, the "2" right, the "3" down.

Glue the coals, the diffusors on the plate.

Solder four wires to the display.

Solder the wires to the DFplayer and connect the speaker.

Solder the wires to the "Hour" "Minute" "Setup/Stop" buttons.

The wires (yellow and orange) have to be connected to the ESP32 first.

Set the plexi in place.

Screw the "setup/stop" button.

Put the display frame on the display

Glue the seal on the box.

Solder the wires 32 and 33.

These will be used to connect the buttons "Hour" and "Minute"

Solder the "IN" of the first RGB led to the "4" output of the ESP32.

You'll see some little lugs.

All you have to do is spread the case a little to place the plate.

Screw the "hour" and "minute" buttons.

Solder the wires 32 and 33 to the "NO" pins of the buttons.

Solder the wires of the MP3 Player to the 17 and 16 pins of the esp32.

Set the speaker in the back plate.

I used WAGO terminals to connect every 5v/VCC together and every GND together.
