Arduino Challenge

[skimmilk5]

Challenge for you coding junkies out there! Prize is the feeling of glory.

I have an Arduino UNO R3. I want to use it as a "keyboard" of sorts (macro keyboard to be exact) for keys and keystrokes that I use the most frequently. Ability to carry out multiple keystrokes with one button press is appreciated, not required. Bonus points if you can add more buttons than headers by using a breadboard.

If you use somebody else's code, please use it with permission, even if it's open source. Be honest!

Create either unique code, DFU code, or clear instructions, all along with a board schematic, including a breadboard, if used.

While you could do this easily with an Arduino Leonardo, it can be done with an UNO R3. I have done it with the help of these sites:

I would check those guides out and if you need more help, search google, it is your friend.

<Rant>

There are literally thousands of tutorials about using an arduino as a HID, not only as a keyboard. This is more like a fun little 1 hour project rather than a challenge.

You wont be able to use an arduino uno as a HID without some mods, for it uses an ATmega328p without a hardware USB interface. For that you need an ATmega which ends with a "-u" like the ones in the Leonardo or micro. The R3 has an ATmega8u as a serial converter, so it can be done just like @Taylor Dettling points out. Just make sure its a genuine R3, most of the cheaper Chinese ones use a CP2102 instead.

Cheers!

Thank you for your comment. I'm completely new to the Arduino world (and software coding for that matter), so it's not quite a one hour project for me .

Thanks for your reply! I am completely new to the Arduino world, so most of the "basic" terminology is confusing to me. I did come across those articles, but I'm not sure how to interpret them or how to start.
