Step 2: Getting to Know Your SunFounder R3 Board
Inside your kit, you’ll find a blue board, seemingly a tiny city filled with small metallic towers and pathways. But
don’t let it intimidate you! This is the SunFounder R3 development board, a kind of Arduino board that can be used to
program and control a vast array of electronic devices and projects.

“off” signals that the board uses to control things like lights or motors.
