#9 Arduino and LED 7-segment displays using a MAX7219 - Part 1

7-segment LED displays are easy to control with an Arduino and a MAX7219 - just 3 wires (plus power supply) and a few lines of simple C++ code. You don't need to be a rocket scientist to display the numbers 0 thru 9 (and the letters HELP) on a 7-segment LED display unit. So you can display the temperature or distance or... you get the idea! It's simple so just watch this and follow me through the steps. Part 2 (video #10) follows on from this one. Subscribe so you don't miss it. All code (for all three video parts) can be found here: https://github.com/RalphBacon/MAX7219-7-Segment-LED -- If you like this video please give it a thumbs up, share it and if you're not already subscribed please do so :) My channel is here: ------------------------------------------------------------------ https://www.youtube.com/c/RalphBacon ------------------------------------------------------------------ How can I remember this?
