2/11/2009Arduino 4: Counting Events. Posted on December 11, 2009 | 4 You need the resistor to ground so that when the button is not pressed, the Arduino pin reads LOW (0V, which is ground) and not some random voltage. The code follows: A variation on this idea is to repeatedly count through a sequence of numbers, like 1-2-3-1-2-3-1-2
Digit 7-Segment LED Display + Arduino: 3 Steps
The sketches pasted below send 70 numbers from processing to arduino. At this point the code contains several irrelevant bits and pieces (it's a work in progress). However it's simple and it works, and if you're struggling to send stuff from processing to arduino, hopefully it'll be helpful.
