I love these OLED displays. Blinky lights seem like such an outdated way to communicate in comparison.
Someone needs to show this to the manufacturer of my furnace, who thinks a single LED with 25,432 slightly different blinking error patterns is sufficient in the year 2016.
Thank you for listening.
