Hi, I have been trying to set up a console to read data from sensors on a "dashboard" of sorts.
Since everyone seems in the dark about my other post, on connecting Bluetooth for serial, I was hoping to use a matrix LED board.
My intention was to have a square lit in the middle, to indicate sensors are functioning. The LEDs around it were to light closer to that square to indicate how close something is to the sensor in that direction. EG: a 5x5 LED matrix, the 4 center LEDs light in a square. If the back IR detects something from the back, the bottom row lights up, or second from bottom row lights up if something is IMMEDIATELY close to the sensor.
In the process, I realized that most matrix LED boards are REALLY small, like ~1inch. I only need around 5x5 LEDs,or maybe in the range of 7x5. It needs to communicate somehow through IC pins, because the Edison doesn't have a display, and IDK if it would work with a shield, even though it's on an Arduino board.
Does anyone have a suggestion of what to use, because I'm trying not to spend my wallet on one (safety) feature for the project, and the only remedy I have so far is to put a 1inch matrix in the console with a magnification window over it: Pretty tacky for showcasing, and even more impractical.
As always, thanks!
