I combined input and output devices so that I could expand on a project that a friend and I have started. The original, long term plan was to make a table that can sense when you put down a cup or something and light up in response. This is a mini version of that.
The first iteration was put together in arduino, where each “pixel” of the table consisted of four LEDs. Sensors (borrowed from a friend) translated the proximity of objects on the “table” into lighting up the four LEDs.
There is tons of online support for arduino, with helped tons with the code, layout and debugging.
Connecting the arduino, breadboard, resistors and LEDs took awhile, and the soldering job took a lot longer than anticipated.
But once it was all done, the table worked...kind of.
