Most advanced electronics PCB assembly lines have pick and place machines to pick components from an SMD reel and place it on a PCB. But this is not possible when you are doing medium-scale production ...

Change the position of a servo motor based on the amount of light. This sketch uses code from SparkFun Electronics sketches for example circuit 6 and 8, version 2.0 6 ...

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 ...
