ATTINY85 Programmer Using Nano

This is a programmer for an ATTINY85 using a Nano as an ISP. There are any number of Internet articles on how to build these. My contribution just provides one way to accomplish mounting and connecting everything.

This device provides a way to upload a sketch into a DIP8 ATTINY85 using a USB connection from a PC or laptop running the Arduino IDE. The Nano provides the necessary interface between the IDE and the ATTINY85.

As always, friend and former co-worker WTS provided copious amounts of advice, help and hand-holding along the way. He understands this kind of thing far better than I do and many of my designs wouldn't be published without some assistance from him.

Before using the programmer the ArduinoISP sketch must be uploaded to the Nano in the normal fashion, programming it to function as an ISP for the ATTINY85. The ArduinoISP sketch is located in the Arduino IDE under File>Examples>Built-in examples (#11 in that list in IDE versi
