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 ...

In this experiment we are going to work with a sensor which is a resistor that depends on light. In a dark environment, the resistor will have a very high resistance. As photons (light) land on the ...

Arriving home to a dark house with an armful of anything is usually an exercise in fumbling confusion until someone manages to turn on a light. [Pavel Gesyuk] has circumvented this problem entirely by ...
