The Awesome Button

Posted by Roblimo on 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.

  7. The HID interface is nice. by Animats · · Score: 2

    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.

      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.

      Your example is wrong. Square is slang that everyone understands is an expression. The fact that I'm square does not cheapen the meaning of the shape. Whereas, the expression awesome has taken over the original expression. Most people do not actually know what awesome means.

    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.
