If you bridge the middle(PIN You can also re-flash the Attiny25 to a different CIC type using an Arduino Uno running [this sketch by Adafruit](https://github.com/adafruit/ArduinoISP). 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. + ![image](https://dl.dropboxusercontent.com/s/umuau0ctbi1orde/arduinoispreflash.jpg?dl=1) ![image](https://dl.dropboxusercontent.com/s/dp4804tihn7qeky/cicrepro.jpg?dl=1)
