Each photocell sensor will act a little differently than the other, even if they are from the same batch. The variations can be really large, 50% or higher! For this reason, they shouldn't be used to try to determine precise light levels in lux or millicandela. Instead, you can expect to only be able to determine basic light changes The cmd_response sketch is very general with respect to the ANALOG IN and DIGITAL I/O of the Arduino boards. We can use it to read a wide variety of sensors from remote computer systems. First, we demonstrate how the Arduino cmd_response sketch works, we construct some simple sensor circuits and then communicate with our Arduino with a Python program (see: Example: Python program sequence.py) This will be achieved by using a photocell sensor, which is a basically a light-dependent resistor. In this project, the light will be modelled with a LED, and the photocell will be placed next to the Arduino board Arduino LDR Sensor and Relay - Connection Diagram. After connecting the Arduino as shown above, we need to test it by uploading the final code to our Arduino. The final sketch can be found here.
