. I load the Arduino environment and load the basic/blink sketch. When I upload it to the board, I see the TX/RX lights blink a few times, then the board goes back to the single blinking yellow light and solid green light.
That sounds like the basic blink sketch is running, what did you expect to see?
I was thinking about it last night and it dawned on me that I probably need to have an LED connected to one of the output pins. After looking at the code and another search, I found this tutorial which confirms what I thought. I was expecting to see one of the onboard LED's light up. Had a DUH moment! Thanks for the suggestions!http://www.arduino.cc/en/Tutorial/BlinkingLEDThanks,Nick
Any recommendation on the size of the current limiting resistor to put in series with the LED?
My ultimate plan is to build a race timer for a Lego Mindstorm race we are going to be having in January. Any recommendations on a segment board that will easily integrate with the arduino's output? I have some basic knowledge of electronics from college 20 years ago when I was pursuing a EEE degree.
