This sensor allows us to interact with the external environment, through intensity of light. The photoresistor is based on light resistance, it will sense the light and will allow the microcontroller ...

[Fjord Carver] brings together an RGB LED and CdS Photoresistor ... This time around it’s an Arduino doing the measuring instead of a PIC. So why isn’t that sensor shown in this picture?

Nano Sensor Interface * Arduino Nano (v3) in Sleep Mode * T.K.Hareendran/2018 ... The trigger pin can be connected to an external sensor, a Reed switch, or a photoresistor, for instance. It is often ...

You can throw a Raspberry Pi camera and OpenCV at the problem and approach it through software, or you can buy an off-the-shelf RGB sensor and wire it up to an Arduino. Or you can go back to ...
