[Hugh] has been going back through episodes of the Hackaday podcast, and Elliot mentioned in episode 67 that it can often be inspiring to go back through the archives of Hackaday to find ideas for new ...

AGC (automatic-gain-control) amplifiers use the nonlinear characteristics of control devices. The magnitude of the real component in some of their differential parameters changes depending on ...

Photoresistors, also commonly referred to as light-dependent resistors (LDRs), are a class of variables resistors which change their resistance depending on how much light is hitting the resistor.

[Fjord Carver] brings together an RGB LED and CdS Photoresistor to make a color sensor. Those Cadmium Sulfide lights sensors usually have a very wide swing of resistance when exposed to varying levels ...

In this experiment we are going to use a element called photoresistor. This sensor allows us to interact with the external environment, through intensity of light. The photoresistor is based on light ...

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

Ambient light sensors (ALSs) are photodetectors that approximate the human eye’s response to light intensity under a variety of lighting conditions and through different attenuation materials. They’re ...
