In the last lesson you learned about using the analogRead() function to collect data from a sensor connected to one of the Arduino’ analog pins.  The range of data we received from the analogRead() function, was mapped from 0 to 1023.  What if we wanted to know the actual voltage being applied at the pin?…

Knowing if something is on or off can be extremely useful, but often you will want to know more.  How bright is the light?  How fast is the satellite moving?  These types of answers are often analog – they cover a large range of values, not just on or off. The Arduino handles analogs inputs…
