Arduino Interface I programmed the board using the Arduino IDE. I opened the Button sketch from the examples menu and changed the pin assignments to match the pins on the "Hello Button" board. I changed the LED pin from pin 13 to pin 7, then selected the USBtinyISP programmer from the tools menu and uploaded the 'Blink' sketch to my board. I changed the code so the LED would stay on for 3 seconds (3000 milliseconds), off for 1/2 second (500 milliseconds), continuing that way forever.
Working helloecho The LED lit up according to plan. I'd like to program more elaborate sequences based on lighthouse/morse code signaling.
