Don't forget to connect Pin 9 of the Arduino Uno to Pin 2 of the ultraCIC to provide a clock signal. Don't forget to connect Pin 9 of the Arduino Uno to Pin 2 of the ultraCIC to provide a clock signal.
Furthermore, many Arduino boards (e.g., UNO, Mega) require a 10µF electrolytic capacitor between RESET and GND, with the positive (long leg) connected to RESET. The capacitor prevents the "master" Arduino from resetting when the serial port is opened. If the board resets, programming will fail.
