I have an idea for a project (for school) that includes the usage of photoresistors. I’m new to Arduino but I have time to learn how to use it, but before I try and continue with this project I would like to know how many photoresistors can I connect to an arduino unit and if there is a way to increase the maximum (staying within a $120 budget mind you; it’s a group project so the cost is split).
Currently I would like to be able to utilize 6 photoresistors and be able to send information to my computer from these resistors. I plan on taking that data and running it through a program and depending on a combination of true-false statements I would create outputs (basically if they are receiving above a light level or not).
If this is possible please let me know, I’ve only seen people connect a single photoresistor from a breadboard → arduino → computer and noted there is a finite number of ports on the Arduino that can be accessed so I’m sure there is a limit but I’m not sure what it is.
Also, is there a way I can circumvent the Arduino entirely and connect the breadboard to my laptop?
