What components have purchased and proved useful / useless?
I have a Raspberry Pi and was not helpful. It is still very popular.
I did not understand why.
At the same price as Raspberry Pi you can buy a tablet. It has in addition touch display, WiFi, battery.
And a better processor.
Raspberry Pi say that is made for automation. Has those ports GPIO.
But anyway those pins can be switched at to small speed that a simple USB device that would have solved the problem.
