6 Frequently Asked Questions about “Make your own photocell”
How to use a photoresistor (or photocell)?
How to Use a Photoresistor (or Photocell) - Arduino Tutorial: A photoresistor or photocell is a light-controlled variable resistor. The resistance of a photoresistor decreases with increasing incident light intensity. A photoresistor can be applied in light-sensitive detector circuits, and light- and dark-acti…
How do you use a photocell?
Photocells are pretty hardy, you can easily solder to them, clip the leads, plug them into breadboards, use alligator clips, etc. The only care you should take is to avoid bending the leads right at the epoxied sensor, as they could break off if flexed too often. Noisemaker that changes frequency based on light level.
What are photocells & how do they work?
Photocells are sensors that allow you to detect light. They are small, inexpensive, low-power, easy to use and don't wear out. For that reason they often appear in toys, gadgets and appliances. They are are often referred to a CdS cells (they are made of Cadmium-Sulfide), light-dependent resistors (LDR), and photoresistors.
Are photocells a good choice?
For most light-sensitive applications like "is it light or dark out", "is there something in front of the sensor (that would block light)", "is there something interrupting a laser beam" (break-beam sensors), or "which of multiple sensors has the most light hitting it", photocells can be a good choice!
What is the size of a photocell?
Size: Round, 5mm (0.2") diameter. (Other photocells can get up to 11mm/0.4" diameter!) Sensitivity range: CdS cells respond to light between 400nm (violet) and 600nm (orange) wavelengths, peaking at about 520nm (green). As we've said, a photocell's resistance changes as the face is exposed to more light.
How do I connect a photocell to a 5V power supply?
Connect one end of the photocell to 5V, the other end to Analog 0. You may want to try different pulldown resistors depending on the light level range you want to detect! This code doesn't do any calculations, it just prints out what it interprets as the amount of light in a qualitative manner.
