I have been searching around for instructions on how to connect a 7 segment LED (in fact i need 2 juxtaposed, but that should be 'easy'.)
(To display numbers up to 10)
I find many examples, but the more i find, the more i get confused as to the best way to proceed.
As i need 2, i would like to limit the number of GPIO pins, because i need some for extra devices.
What would you recommend to a beginner:
- Start with 2 simple Leds, add a "shift register" (whatever that is) and limit the GPIO's to 2 x 3 ?
- Buy some "backpack" exquipped ones, if i can find them...
