Countdown Clock intended for Robot Combat Timer

Currently under testing, the 3d model printed fine and is usable.

• Digits are 300mm tall, to print you will need a printer that can handle 300mm x 200mm.
• It is very bright, images are at 10% brightness.
• Each segment used 6 leds from a 60 leds/m strip.
• Screw holes that hold down the backplates are designed for a m3 scew up to 10mm (i used m3x8) and a m3 threaded insert.
• Scew holes that hold the seperate digits together are m6x8 or longer.(m6x6 would work in a pinch.)
• programmed using VSCode and PlatformIO, but could easily be copied into the arduino IDE.

Current functionality

• can display 0-9 on a single digit
• It gets the time from an NTP server.
• displays the 0s place minute digit on the 7-Segment Display
• colors the 0s place digit with the 10s place minute digit
