Blink Example

If you are using a SparkFun Pro Micro 5V/16Mhz and tried to open the Blink example you probably noticed that nothing happens. This is because the code is set to control Pin 13 and there is no Pin 13. So wire an LED to Pin 2 (it’s written on the PCB) and change the code to use Pin 2 in line 10.

Can’t upload a sketch to a SparkFun Pro Micro 5V/16Mhz??

At the time of writing, if you follow the instructions given here then it mentions that you need to download the ProMicro-Addon-190612.zip. This file didn’t work for me however I came across info that ProMicro-Addon-240112.zip worked for someone else and it worked for me too.
