Morse code transmitter/reciever

Introduction
I made this for my friend because she likes morse code (no facking way) in the last week summer holidays and i almost went crazy because there was so many problems that i just didnt expect and it facked me up little bit but its ok im fine. At the we had fun with it .

What does it do
This piece of art has two modes and one inbetween:

Creating message

Mode switches by switch
You write the message using digital touch sensor on 4x4 neopixel matrix.
You make dot by short/no pause between touching sensor and dash by making pause that is longer then 1 second, basically you arent making diffrence(dot x dash) by touching the sensor for certain amount of time but you just touch it quickly and then wait.
You make gap by turning potentiometer to other side for second and then turning it back.
You delete message by turning potentiometer to other side and then touch digital sensor (if you wont touch it, it will create a gap)
Message can be more then one page long(4*4+)
