I had a look at the new Arduino Project Hub. While the idea is great it is in danger of turning into another Instructables site with totally crap projects. There is, or should be, some expectation that the projects featured at least work, and then that they are designed in such a way as to not damage your Arduino.
I came across this mess:-
Not only was the Fritzing layout totally unfollowable there had been no attempt to route the schematic portion of the Fritzing project. When I did untangle it the circuit was a farce.
Trying to drive 8 LEDs from one pin with current limiting of two series diodes. The LEDs the wrong way round, and the switch pull down resistor going to ground through a diode.
Should there not be some sort of minimum standard for submission to this Project Hub? It is only going to cause a lot of confusion to beginners. I think it is important that beginners start with solid well documented examples. With at least a schematic that can be read.
