I'm confused about how and when to use the reset button on the Arduino. Do I simply press the button while it is on? Is it simply restarting the board or clearing the uploaded code as well? Currently when I press the button while my Uno is powered it does absolutely nothing.
I have been using this board for many weeks with no problem and just now I have been getting this error:
And I cannot upload code. I tried using the reset button but I see nothing happening on the board, no blink, no flicker, nothing indicating something was reset.
