The Awesome Button 80

Posted by Roblimo from the learn-by-playing-around dept.
An anonymous reader writes "An awesome hardware hack which demonstrates how easily USB-based human interface devices (eg, Keyboards and Mice) can be created using the Arduino software environment." A very nice little project based on the Teensy USB Development Board. Reminds me of the breadboard electronics projects my Dad used to work on with me many years ago. "Great fun for young and old," you might say.

      This isn't V-USB, which requires pretty advanced C programming knowledge. It's based on the Arduino software, which makes it far easier and more accessible.

      Sure, the final result is the same if you're in that elite C coder camp, and you probably even view Arduino as a toy not worthy of your attention.

      But for the rest of us, Arduino makes the things that ought to be easy, well, easy. You could even same it's awesome^H^H^H^H^H^H excellent.

        Arduino gives you all the pieces you need to start using microcontrollers - hardware and software environments, lots of contributed libraries and applications. If you want to write stuff from scratch you can, but if you want to get started building your blinky-light thing, it's all there, and then you can go on to more complex projects. It has a few limitations (Teensy gets around the USB-vs-serial issues, for instance), but it's pretty complete and extremely expandable. If you're more interested in tweaking bits, you can use many different tools, but if you're really trying to add blinky lights to your backpack or move the servo arms on a robot thingy or program the lights on your Christmas tree to respond to music or controlling your thermostat, you can use the Arduino tools to do that without diving into the bit-bashing first.

        And yes, you could have just bought the AVR ATmega chip yourself, but then you'd have needed a in-circuit chip-programmer device, which costs just about the same as an Arduino, and you can load a program into the Arduino to make it be a chip-programmer, so you might as well buy the Arduino anyway.

        There is nothing wrong with slang. However, sometimes slang cheapens the original meaning of a word. I use awesome as slang often enough myself, but it should be reserved for things that are truly awe-inspiring. Things like the notion of God, the universe, even the holocaust (which demonstrates a negative thing that is still awesome). Using the word as slang is fine, I'm not the language police. However, overusing adjectives and thinking that they all mean the same thing is terrible.

    Yes, the USB HID interface is quite easy to use. I've dealt with it from the other side, using a Logitec steering wheel, mouse, and pedals to control a robot vehicle.

    Force feedback via that interface is lame, though. I wanted to have the steering wheel track what the vehicle steering was actually doing, so you'd feel the resistance of the real steering. You could spin the steering wheel, and it would take a second or so for the real vehicle's steering to catch up. But the HID interface for steering wheels is more like an audio device, intended for vibration, not positional feedback.

    Incidentally, you can have many HID devices, and they don't have to pretend to be the main mouse and keyboard. Applications aware of them can use them for other inputs.

  • Think of the custom game controller possibilities for PC-based gaming.

    With some custom DIY mechanical design you could make foot controls, chair arm controls, etc all fed through the keyboard interface.
    This little USB gadget makes it much easier.

    Awesome!
    • You also use a 2 dollar throwaway keyboard, rip out the print board and solder directly to a keyboard interface. Sure you loose the keyboard codes that you use but its cheaper, easier, and entirely not my idea. But I am using it to make me an SNES pad to USB.

      • Every keyboard I've seen have a huge circuit board, how to do deal with that? It would seem the teensy would be better, it's already small, and maybe less prone to failure vs. using a cut-up keyboard circuit board.

        Right. Were it not for the fact that many arduino projects don't see themselves as Hello-word-tutorials but as clever hacks.
