Finished my Display board application

Project was to display tide information (time and height) on an LED panel. Fingers crossed the image loads!

OK, it's not an Arduino as such, it's an ESP32, but I programmed it on the arduino IDE. I get the time from an NTP time server and tide data from an API. A bit of messing around with daylight savings times and I display the next four tides on the Hub75 LED matrix. Date and clock is shown on the other side. Every 24 hours I pull new data down and sync the clock.

The good: It works as planned.

The bad: API keys and wifi creds are all hard coded so will need a firmware update if either change. Don't think I have sufficient pins left to allow me to read from an SD card.

The ugly: The wiring behind it is not beautiful. The code could do with a review and tidy. - Maybe even a bit of error handling wouldn't go amiss. Red and Blue are a bit jarring so close together and the blue is a bit swamped , especially when the brightness is turned down.

I may make an enclosure to keep it all together and keep the dust off and add a pir sensor to turn the display off when there's no movement. Or I may get bored and dismantle it!
