Yesterday I began taking some baby steps with Hodor and the Arduino as part of my Rube Goldbot project. I went from getting the on-board LED on the Arduino to blink on and off to getting it to spell out HODOR in Morse code, and finally got a single LED OFF of the Arduino blinking out Hodor. Today I wanted to take another step – this time having each letter (D, H, O and R) in Hodor’s name be a separate LED and be able to Morse out the letter. This step is important because eventually I’ll want to have individual control over each key of myRead More →

If we think of projects as our children, then I am a parent who is completely unprepared. This is very true of my baby Hodor, who is going to be the brawn of my World of Warcraft playing robot, Rube Goldbot. I don’t know anything about the underlying technology I’m going to use to make him, the fore of which is the Arduino. Conceptually, of course, I get that the Arduino is a microcontroller – it is capable of doing some computation and then sending signals out to other electronic parts who have names and purposes I don’t know anything about either, but at least this knowledgeRead More →

For my Rube Goldbot project I need a bunch of hardware. Rube’s eyes (Uatu) and body (Hodor) are going to be controlled by a Raspberry Pi and Arduino, respectively, and will use a bunch of other parts as well, but the core will be those microcontrollers or whatever they’re called. I had an Arduino Uno kit laying around that I’d never used – I got it a couple of years ago on an impulse buy because it was 50% off. I also hit up Amazon for a Raspberry Pi kit, some MOSFET transistors (not entirely sure what those do yet) and other parts. Finally, when I wasRead More →

So far there’s a rough idea of the eyes and brain for Rube Goldbot but now we need something that can carry out the actions that the brain thinks should be taken. This is the doer – it DOES stuff. In this case, it’ll send keystrokes, mouse movement and button clicks to the computer running the WoW client. The doer doesn’t need to make any decisions. All it needs to do is execute what it is told. If the brain says “press shift+1” the doer presses shift+1. It doesn’t need state, it doesn’t need anything but instructions and the ability to carry them out. There are a lot ofRead More →
