Unfortunately, a common mistake beginners make is frequently perpetuated by this forum. We tell beginners to get an Uno, even when we know they want to build circuits from components, not to plug in ready-made shields. We should recommend Nano or some other breadboard friendly Arduino in these cases.
What I am forever pointing out. :cold_sweat:
But it is not so much the forum, but the website. The UNO is the "flagship" of Arduino which is the originator of the "Start with a UNO" meme. The design concept is you use a UNO and there is a "shield" to do whatever you need to do. However it was to start with, this is really no longer the case; there are some applications for which a shield does the job, but most projects rapidly expand beyond the capacity of the shields.
It is annoying when a "newbie" is advised to "get a UNO" after asking a "beginner" enquiry, but such advice just as often comes from another "newbie". :astonished:
