This example illustrates how to measure the light sensitive analog voltage from a photoresistor circuit connected to Pin 0 of an Arduino Uno.
The example then applies three types of calculations in real-time to determine if the current voltage reading signifies motion.
Using a pre-recorded dataset, the data is further processed in MATLAB to categorize the motion.
This example requires the user to first install the MATLAB Support Pacakge for Arduino Hardware which is available here:

Hi, I might just be reading the code wrong but it looks like you've used a function 'getSlope' on line 93 of the 'Run_Motion_Detector' function. When I try to use this code it throws up an error saying it is an undefined function or variable. Am I missing this function in an update or has it been replaced by a recent update? I'm using 2019b.
