I have started this joystick controller experiment inspired by the need of a simple DIY joystick which could deliver greater flexibility in the possible designs. Hardware component basis is very ...

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 ...

To interface a Analog input (angular displacement sensor POT) and scale the values up on change in the input. Analog signals – directly measurable quantities in terms of some other quantity. Examples: ...

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.

Here is a useful circuit for Arduino lovers and experimenters. It is a simple digital voltmeter, which can safely measure input dc voltages in 0 to 30V range. The Arduino board can be powered from a ...

Before I start talking about this really cool thing called Arduino (Italian for "good friend"), let me say a few things about the fascinating subject of physical computing. Physical computing has been ...
