This was my CPSC 599.88 - Tangible UI Assignment 1. I had to make a button and an LED light, then take my own creative spin on it. Imagine you're on a sinking ship and your life vest has radio equipment attached. After sending an SOS, there is no more use for the equipment. That's where my project comes in.

I used 5 outputs of 4 LED lights, red, blue, yellow and white, and a piezo speaker. I used 1 input of a button. The user is able to use morse code to send codes to the LED lights to turn on certain sequences to show a message. The piezo speaker is used to replicate the sound of the user inputting morse code.

The button has a timer to detect how long it is being pressed. If it's a short press (less than 250ms) it is a dot and if it's longer it's a dash. The program will translate the morse to a letter and after receiving 3 letters it will carry out the code attached.

There is a total of 6 codes the user can input. WAT for "watch out" will turn the red light on. HOW for "How are you?" will turn the white light on. BAD for "Bad" will blink the white light. GOO for "Good" will turn the blue light on. COM for "come here" will turn the yellow light on. Finally, RAV for "Rave Party" will blink all the lights.

My project is different because I stuffed my electronics inside a jacket. I wanted to get a good idea in the first assignment about embodying my circuitry as it is the first time I've done it. I think using morse code is a slight bonus from just pressing the button as it makes timing important.
