Morse Telegraph Key Coaching

This is a customized version of https://www.thingiverse.com/thing:4207626
I designed it because my kids are interested in Morse code.

I have integrated a push button, a display and an Arduino. The display shows the Morse code in the first line and translates the code into letters in the second line. When the line is full, the display is cleared and you can start again.

The following parts are needed for the construction:

* 1 x Oled Display (1,3")
* 1 x Arduino Pro Micro ( USB-C)
* 1 x Mechanical Limit Switch ( as used in most 3D printers)
* Small Buzzer (Optional)
* Some 3mm screws and nuts
* 2 x 5mm screws and nuts

Wiring:

Connect Pin 9 of the Arduino to the limit switch. Connect the display (SDA,SCL) to PIN 3 and PIN2. Optional: connect the buzzer to PIN 6.
