If the boards are visible, select the option that matches your board. If you
have a Pro Micro, make sure you select the correct operating speed and
voltage! Then head over to the next page where we’ll upload our first
sketch!
Example 1: Blinkies!
The Arduino-standard Blink sketch won’t have any visible effect on the Pro
Micro – there’s no LED on pin 13. In fact, the only LEDs on the board are
the power indicator, and RX/TX blinkies. Unlike other Arduino boards,
though, we can control the RX/TX LEDs in our sketch. So let’s get blinking!
Upload the RX/TX Blinky Sketch
Copy and paste the code below, and upload* it to your Pro Micro.
