I imagine you’re here because you have heard about the internet enabled fish tank, the world’s most advanced taking aquarium. I made it as a one-off project purely to push my technical skills to the limit and create something awesome. I had a vision and loads of crazy ideas of what I could make it do, some seemed way beyond my level of technical skill. I’m happy to say I proved myself wrong. I’m really happy with how it turned out. Naturally there’s a few bits I’d like to neaten up or spend more time on, but overall it’s a finished project.
These LED panels take care of all the work of making a big matrix display. Each panel has six 8×8 red matrix modules, for a 16×24 matrix. The panel has a HT1632C chip on the back with does all the multiplexing work for you and has a 3-pin SPI-like serial interface to talk to it and set LEDs on or off (you cannot set the LED to be individually dimmed, as in ‘grayscale’). There’s a few extras as well, such as being able to change the brightness of the entire display, or blink the entire display at 1 Hz.
