10 photocells light dependant resistors circuit bending
.....the secret, of any GREAT Modified Device
LARGE DYNAMIC RANGE to 20 meg resistance+
you Get 7 regular size, 2 metal encased, and 1" MONDO CELL
THESE are Pro Cells, and not RADIO SHACK TYPE
LDRs or Light Dependent Resistors are very useful especially in light/dark sensor circuits.
Light Sensitive Photonic Detectors-Photoresistors or Light Dependent Resistors (LDR) which change resistance when illuminated
Photosensors or photodetectors are sensors of light or other electromagnetic energy.
A photocell is a type of resistor. When light strikes the cell, it allows current to flow more freely.
When dark, its resistance increases dramatically.
(CIRCUIT BENDERS use LDR's instead of a POTENTIOMETER or TOGGLE switch) BAMM!
They can be used to detect large or small fluctuations in light levels to distinguish between direct sunlight (STAGE LIGHTING) and total darkness, or anything in between.
For circuit bending, circuit bent devices, Robotics, circuitry repurposing,
Modification of Audio instruments, children's toys, or any electronic DIY ELECTRONICS' Project
Vary the pitch, speed, voltage, or volume of any electronic ANALOG or DIGITAL audio device
BUILD a VACTROL with an added LED, Pitch tune a toy-!
