In Arduino applications often the 'raw' value of a sensor is mapped upon a more usable value. E.g. the value of analogRead() 0 .. 1023 is mapped onto 0 .. 5.0 Volt. This is often done by the map ...

To solve the problem this library provides a set of preprocessor functions that statically map AVR IO registers to corresponding pins in 8bit AVR based arduino boards as well as standalone AVRs. By ...

The outputs from the potentiometers are analog, so they can have a value only between 0 and 1,023 when read by the analog pin of the Arduino. This number sends a pulse to the Arduino, which in ...

If you’d like to get more specific, Michael Klements’ Arduino-based scanner lets you quantify colors in numerical RGB values via a TCS34725 sensor. User interface for the handheld device is ...
