I thought about what ‘unexpected’ was supposed to entail for a long time. I was thinking about what could be ‘unexpected’ from an LED and all I thought about was it not blinking. After much contemplation, I began to think about using a photosensor. My first inspiration was glasses that would shine a light when it was dark, for no reason. But then I began to think of when glasses/goggles would be used along with light. My first thought was of mine workers. Soon my mind (unfortunately) drifted towards morbid thoughts, like how some mine workers would be stuck in the dark if the mine caved in. Considering the recent news, I also thought about the earthquake in Taiwan that trapped several people in rubble.

Soon enough, I decided to make a photosensitive light that would morse code H-E-L-P when the surroundings are dark. I made it in hopes of allowing victims to be more easily found, as people cannot scream for help for a long time.

I set up the RedBoard ‘normally’:

I then looked online on how to morse code H-E-L-P:

H = dot, dot dot, dot , E = dot , L = dot, dash, dot, dot , P = dot, dash, dash, dot

With some help, I was able to code the following (sorry for the bad quality, will learn how to use the website for next time):

This is the video of it working:
