This is very basic because I am starting from scratch with my knowledge of the Arduino. I wrote basic programs in the late 80's but haven't done anything since then.
When a sketch is downloaded to the Arduino I am assuming it has to be initiated to start running. If that being true, is there a way to start the sketch when the Arduino is power up. Without any manual initiation?
Thanks for your patience!

Either power on or pushing the reset switch if already running will re-initiate the sketch. It will run the procedure called 'startup' first , then if allowed run the procedure called 'loop' forever or until power is removed or the reset switch is pushed again.
Open the IDE, and open the Blink example (see attached pics for the steps) Notice the only two procedures startup and loop. Startup is executed once for each reset or power on, loop runs forever or until reset is pushed or power removed.
