Hello,
I'm currently trying to build a board that will show which part of the earth is light/dark. I planned to uses 64 5mm LEDs. My idea is to calculate for each led if the sun is up according to the longitude/latitude with the timelord arduino library.
I'm planning to use the MAX7219 to control the leds. Around 30-40 LEDs should be constantly on. With a new calculus every 5-10 minutes.
Do you think I thought this correctly. Is there any issues I didn't plan ?
Thank you,
