A sensor is a device that transforms physical quantities like temperature, humidity, pressure, etc., to an electrical signal. Moreover, this signal is often fed to a microcontroller like the Arduino for further processing, displaying or recording. This data from the sensor are often analog in nature, i.e., they vary over …

One of the strengths of the Arduino platform is its extensive library. Libraries make life simpler for coders; imagine how hard it would be if there's no LiquidCrystal or Servo library ready for use. In my experience, projects took shorter time because of the built-in and third-party Arduino library you …
