What is the differences if I just select Arduino/Genuino Uno instead of Maker UNO?
Arduino/Genuino Uno by default will set all IO pins to INPUT. If you upload a Blink example
to Maker UNO, you will get LED 13 blink and also other LEDs light up randomly,
(some mes all LED turns on). This is because INPUT is floa ng, as long as you don’t set
those pins to OUTPUT or connect to external circuit, it will produce a floa ng voltage (can
be 1V, 2V or any voltage in range of 0-5V). This floa ng voltage some mes is enough to
light up the LED. Actually this is not a problem, just making confusion for newbie/beginner
to start learning using Maker UNO.
We create a custom board package for Maker UNO to cater this confusion. What Maker
UNO board package do is to ini alize all digital IO pins to OUTPUT by default. So when you
upload Blink example, only pin 13 will blink, other pins will remain off. This approach is
good for newbie/beginner, HOWEVER we advise to use this method only for early lesson.
Once you already understood regarding INPUT and OUTPUT, we advise you to select
Arduino/Genuino Uno as a board for safety purpose.
