Everything I see is one UNO being used for like one item. I see all the inputs and output we can use and have tried to use at least 4 or 5 PIR's to activate store-bought Halloween props. Basically use the "Try Me" button circuit. Might use relays to trigger the prop once the PIR is triggered. I'm looking at the "millis()" code to see if it improves the response time.
Can the UNO be used for multiple inputs and outputs? I noticed in the Stimulator in Tinkercad I have slight delays as the PIR's are triggered.
I may change it to using the PIR's individually with each prop.
As a newbie to programming, I'm just seeing what can be done. Any Thoughts?
