IC Station DS1307 Real Time Clock

In this tutorial, we will be using the IC Station DS1307 Real Time Clock Module. This will allow you to not only build a clock display, but add date and time stamping functions to your projects, so you know when

Arduino Map: Floats or Ints?

The Arduino Map function is a very useful function. It allows you to map a input range from a analog sensor to another set of values. For instance, lets say we have a fuel gauge, with a varying resistance. We

Debouncing Switches

Very often we need to connect some type of mechanical switch to an Arduino as an input device. Also very often, there is mechanical slop in a switch, so the arduino sees one activation of the switch as multiple activations.
