Transmissive optical sensor without aperture Vishay TCST1000/TCST2000
by Diana Fernandez

Demonstrates how to use a transmisive optical sensor. This sensor is used in mechanisms to detect when the gap in the top is blocked by an object. When the sensor detects an interruption the Wiring onboard LED is turned on.
