I've built a basic two button analog joystick driver for the UNO that turns the UNO into a USB joystick. This is based on the joystick demo from the ...
I've updated the Keyboard firmware to support key usage codes greater than 101. The maximum code is now 231 so you can send all of the key usage code...
I received my Arduino UNO from Sparkfun on Thursday, and I've been blown away by how easy it is to use. I've created Keyboard HID firmware for the UN...
I've added MIDI IN support to the USB MIDI driver so now the UNO can send and receive MIDI messages from the host PC. The format of the data is the s...
My April Fools joke hit a roadblock when I discovered that my coworker was using an old PS2 keyboard rather than a USB one. I had to work out a solut...
I decided to make use of the Keyboard HID driver in a proof-of-concept project. The project: connect a USB keyboard to the Arduino and have the Ardui...
I've put together a basic USB MIDI driver for the UNO's atmega8u2. I've tested it using the demo sketch below with GarageBand and it seems to be work...
I've created a Mouse HID driver for the UNO's atmega8u2. It makes the Arduino appear to be a USB mouse device, and lets it move the mouse and send bu...
I've updated the keyboard driver so it no longer needs delays in the sketch when sending keys. Here's the updated firmware, source, and an example sk...
