#253 ATtiny Programming Shield

A custom ATtiny programming shield for use with Arduino ISP

Build

Notes

I covered programming an ATtiny with the Arduino ISP in LEAP#070 Programming an ATtiny With ArduinoISP.

Since I’ve been programming a few more ATtiny processors, and simplify the processing of programming an ATtiny with ArduinoISP, I wired up a strip of protoboard to serve as a custom programming shield. This is the layout I chose:

ProgrammingShield_layout

It’s designed to be snapped onto an Arduino UNO, lined up with GPIO digital pins 8-13.

It includes two LEDs on PB0 and PB1, which can be used for debugging/testing a program loaded on the ATtiny.

Construction

Designed with Fritzing: see ProgrammingShield.fzz.

About LEAP

LEAP is my personal collection of electronics projects - usually involving an Arduino or other microprocessor in one way or another. Some are full-blown projects, while many are trivial breadboard experiments, intended to learn and explore something interesting.

Projects are often inspired by things found wild on the net, or ideas from the many great electronics podcasts and YouTube channels. Feel free to borrow liberally, and if you spot any issues do let me know or send a pull-request.

NOTE: For a while I included various scale modelling projects here too, but I've now split them off into a new repository: check out LittleModelArt if you are looking for these projects.
