7 Segment Displays & Arduino the EASY way! with MAX7219 Driver

I've got a project I'm working on where I need to drive a ton of 7 Segment displays, so instead of dealing with all of the multiplexing myself, like I normally would, I decided to take the easy route and go with a dedicated LED driver (MAX7219). It runs the whole show and I'll explain how to work with it in this video. Datasheet: https://datasheets.maximintegrated.com/en/ds/MAX7219-MAX7221.pdf The other way I've done it explained here: https://www.youtube.com/watch?v=Ne4Wv1kUP8w The CODE is here: http://www.kevindarrah.com/download/arduino_code/MAX7219_DEMO.ino Wiki for the 328 Board: http://www.kevindarrah.com/wiki/index.php?title=328Board Check out my Tindie store (trigBoard is available) https://www.tindie.com/stores/kdcircuits/ Thanks to all the Patrons for dropping a few bucks in the tip jar to help make these videos happen! https://www.patreon.com/kdarrah Twitter: https://twitter.com/KDcircuits For inquiries or design services: https://www.kdcircuits.com
