The darlington pair family of ULN like the ULN2801A ULN2802A ULN2803A and ULN2804A are pretty common but a bit different in wiring. While it is in itself simple, it's a bit counterintuitive how to wire the ULN2803A.
In case you wanna connect loads to your GPIO pis of your Raspberry Pi, ESP32 or Arduino, a darlington pair is a good choice to protect your GPIOs!
So check out this video where we check out the schematic and a little experiment to see how it works.
But before you dive into this video, make sure to watch the darlington pair basic video for a fundamental understanding of a darlington pair:
