Newbie questions:
Hi, I have a program loaded, and want it to "start" ... my assumption is a take the Tx line high. Once I power the Leonardo using the DC adapter, are the power pins active or are those power inputs ? And in order to trigger Tx, can I simply take Tx high using the 5V power pin or do I need a resistive load in between? Thanks for any thoughts on getting the program to run.
As soon as you load the program it will run.
Or:-
Apply power and the program will run. Or press the reset to get it to run from the start again.
There is no need to do anything else.
On the other hand, if you want the program to start and then wait until you do something you can put a WHILE loop into setup() that repeats over and over while you have not done whatever you do.

Thank you very much
