Incoming Noob question alert!
So, I am new to this platform and I have a few questions.
What happens when I upload a new sketch to the Arduino from the Arduino IDE, the older sketch gets deleted? or older one still survives in the Arduino memory somehow? if it does.. what happens when it runs out of memory? and how do you go about choosing which one to run?I have a feeling that the old one gets deleted, but I want someone to confirm it.
I understand that the there is a void setup () part and void loop () part, the void loop part keeps the thing going indefinitely. Regardless, is there a way to start/stop the program? without cutting the power to the board?
