Exploring the signals behind Arduino's Servo library, and characterizing a servo's response to pulse width.

Servo Signals and Characterization

17K

I wasn't happy with the way the square waves sound, so I explored using other methods of generating sound waves with Arduino.

Generating Audio with an Arduino and a Resistor Ladder DAC

14K

Learn about photoresistors and the process of characterizing their response to light intensity.

Set up an RGB LED to phase through the colors of the rainbow, or use twist knobs to make a custom color.

RGB Light Control with Arduino

25K

Arduino boards don't have analog outputs. But they do have a function called analogWrite. So what is it doing there?

Exploring Pulse Width Modulation

4.4K

Using an Arduino to toggle something like an LED light is simple in theory, but buttons don't always behave the way we think.
