File, Examples, Basics, Blink
Learn the code:
Connect an external LED and resistor
Learn about pseudo-analog, otherwise known as “Pulse Width Modulation” = PWM
Learn to measure voltages with a multimeter. Make an analog voltage using a variable resistor.
Digitize an analog input voltage.
Use the Serial Monitor and Serial Plotter
Run a servo motor
Connect a system: Input, Processing, Output.
Oooh pretty lights! Learn how to find an external library, where to put the file, and how to control neopixels
Write your own code to use an analog input to control neopixel outputs.
