So I am playing with the Arduino UNO board that Robin got me for Christmas. The first example in the book was to make an LED blink once per second. Success. But not with some struggle. Don’t you hate it when the first exams in a book has a very important omission? Like a define statement? Thank goodness these days I can go to the authors web page and and find the needed corrections. So here is my first working program.
So after that hello world program, let’s add a button and check its state. If button is pressed, turn on LED.
