In this video I explain what you need to know about light dependent resistors, LDRs or photoresistors: what they are, how they work and the typical specifications or parameters associated with them.
Photo resistors or light dependent resistors, are very useful components and in this video I'm going to describe the essentials about these useful electronic components.
Light dependent resistors, LDRs photo resistors or whatever you want to call them are a form of resistor that's sensitive to light, - they change their resistance dependent upon the light level.
You may see them pop up in circuit designs from time to time. They have a quite unique circuit symbol. There are two types that you may see.
Light dependent resistors are made from semiconductor materials but they act as resistor. They have a very distinct difference between the light and dark resistance values and this makes them very useful.
However there are a few points to note about the use of these photo resistors or light dependent resistors.
