[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 lev… ...

A photoresistor, which has a VA characteristic that's linear in a large range of voltages, is up to the task. Common photoresistors remain perfectly linear for signal amplitudes of 100V or more.

The number of free electrons is also proportional to the amount of light being shone on the photoresistor, i.e. the greater the light intensity, the greater the number of free electrons and holes. It ...

The photoresistor is based on light resistance, it will sense the light and will allow the microcontroller in this case Arduino to react and change the intensity of Led Diode. The photoresistor ...

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 ...

a: The device structure. b: The on-off ratios (the ratio of conductivity with/without pseudo-sunlight) of the photoresistor devices. The higher the on-off ratio, the better the performance of the ...
