I have been creating with Arduino boards for about two years now and having a blast. It’s been mostly the Uno, and a couple of smaller, REAL ARDUINO boards, and everything has been great.
I ordered some (non-true-Arduino) Pro Micros (ATMEGE32U4). They work great for my purposes, HOWEVER…
Trying to implement some RF24L01 radio boards into this project has now become… “challenging”.
They work PERFECTLY on the Unos (surprisingly easy). However… the connections on these little Micro boards…
According to the documentation/pin labeling… the SCK/MISO/MOSI pins on these little boards are 16/14/15 (see attached).
But according to all of the tutorials and help I have read, these radios “MUST” be connected to pins 13/12/11 which are the SCK/MISO/MOSI pins.
First of all, there are no 13/12/11 pins indicated on these boards.
I… confused… what?.. over-thinking?.. over-complicating?
Ouch. My brain.
