The purpose of this sketch is to demonstrate a form of analog input using the potentiometer Grove. We will use this to set the delay for our blinking LEDs from project one. Connect the LED module to ...

Analog signals – directly measurable quantities in terms of some other quantity. Examples: Thermometer – mercury height rises as temperature rises Car Speedometer – Needle moves farther right as you ...

The Joystick module is similar to analog joysticks found in gamepads. It is made by mounting two potentiometers at a 90 degrees angle. The potentiometers are connected to a short stick centered by ...

There was a time when building electronics and building software were two distinct activities. These days, almost any significant electronic project will use a CPU somewhere, or — at least — could.
