Hey everyone, I'm new to Arduino and have a question regarding PIR sensors. My son's 8th grade computer class has asked him to figure out a way to change the state of his computer (close the program he has opened and then open a different one) after someone enters his room.
My guess is that we could use a Arduino and something like a PIR sensor shield to detect the presence of a person and send a signal to his comohter to run a program that minimizes his current application and opens a different one.
Is that even possible?
Can someone direct us where we can start?
