If you look closely, you will see that I added a yellow wire going from the TXLED to the empty hole that was drilled over by the reset button. I added a single pin though this hole and epoxied the plastic in place to give myself another bread-boardable pin that has access to the PD5 signal which was not broken out. Simple mod really. (more…)
This project had many ups and downs, sadly ending in a down. My greatest strength caused my demise since my aesthetically pleasing container, the Altoids box, is conductor and my LEDs, connected to the side, failed to blink properly. Even though my project didnt end up exactly like I intended, I still learned a lot from this project and had a bunch of fun experimenting with my Arduino Micro.
On Adafruit Learning System there are a lot of cool tutorials and this particular one is based on the Arduino Micro used to upcycles old Next keyboards:
Ladyada and pt had an old NeXT keyboard with a strong desire to get it running on a modern computer. These keyboards are durable, super clicky, and very satisfying to use! However, they are very old designs, specifically made for NeXT hardware, pre-ADB and pre-USB! That means you can’t just plug the keyboard into an ADB or PS/2 port or PS/2 to USB converter (even though it looks similar). In fact, I have no idea what the protocol or pinout is named, so we’ll just call it “non-ADB NeXT Keyboard”

I use a micro, but just about anything will do. There’s some Sugru on there to keep the sharp bits from catching on clothing/pockets. Usb battery powers the whole thing. It’s pretty bright, definitely not subtle.
John Thomson managed to build a pressure sensor to behave like a switch, when it’s in an idle state the LED is off, if you apply some pressure, light goes on:
The pressure pad doesn’t just work straight out the box – it requires a little bit of craft. What I’ve done is sandwich a pressure sensitive conductive sheet – known as Velostat – between two pieces of felt. I then stitched some conductive thread through each piece of felt – this applies a current to the pad and when the sandwich is put together, the circuit is complete. The Velostat acts like a resistor – the value changes when pressure is applied. It’s then just a case of writing out code that tells the LED to come on when the pressure reading goes over a certain threshold.
Steve Yoshida is a systems engineer and worked on a project involving Arduino Micro and Infrared remote adapter:
My new Arduino sat on the shelf for a few weeks before I came up with a quick project that I wanted to use it for. I use XBMC a lot on both PC and Raspberry Pi and wanted a quick way to get IR keyboard inputs from a remote. I had used the IR library for Arduino in the past so I was already pretty familiar with the hardware and code involved. What made the Arduino Micro ideal for this project was the keyboard emulation supported by the board and also its compact size…

Reach is a large-scale interactive mural and musical instrument created for the Children’s Museum of Pittsburgh as part of the Tough Art residency program. There are no visible electronics, but when users touch both the moon and a star (either alone or by holding hands with others) a tone is played.
