Fun with Servos

I recently received two HXT900 servos to play with. I used the sample servo code included in the Arduino IDE, that allows me to control the servo position with a potentiometer. The pot is connected to the arduino, with the

Light Sensing with a CdS (LDR)

A Cadmium Sulfide (CdS) sensor is a Light Dependent Resistor (LDR). It is a resistor that reduces resistance when hit with light. The more light, the lower the resistance. The Arduino is ideal for monitoring one of these sensors, and
