LDR circuit setup

To set up a light dependent resistor (LDR) circuit, we'll need:

  • LDR

    An LDR is also called a photocell or photoresistor. It is special type of resistor. Its resistance decreases as it is exposed to light. The higher the light exposure, the lower the resistance. In a dark room, it has highest resistance. This property comes from physical characteristics of semiconductors used inside. LDR does not belong to a specific company. There is no official datasheet either. You can refer to this webpage for more information about LDR: https://learn.adafruit.com/photocells

  • Male-to-male jumper wires

    We need jumper wires to connect BeagleBone and components through a breadboard

  • Half-size breadboard

    A breadboard is needed to create solderless circuit ...
