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 ...

An analog input pin can read a voltage level that ranges from the supply voltage of your board 3.3 v (3.3V) down to 0 v (GND). The value returned to your program from reading the pin is not the actual ...

In this experiment we are going to use a element called photoresistor. This sensor allows us to interact with the external environment, through intensity of light. The photoresistor is based on light ...

Abstract: The Arduino micro-controller development platform has received a lot of attention from hobbyist (makers) as well as university engineering programs. The ability to perform simple, yet ...
