ir sensor

This section gives step-by-step instructions along with photos to the construction of IR Proximity Switch. Because this is a very simple circuit, only a schematic for the sensor is shown here: (For the PDF format click here. ) This tutorial`s objective was to help others built a infrared proximity switch. Complete construction details and photos ar

e included in this tutorial for the sensor. Once the concepts were conveyed the reader could build an IR switch which could be connected to a robot and be used as the robot`s eyes.
