Ladyada's Learn Arduino - Lesson #2
Venture deep into the Blink sketch...
by lady ada
OK you've gotten your Arduino set up and also figured out how to use the software to send sketches to the board. Powerful stuff! But...just running example sketches is a little boring. What we really want to do is use our own creativity and skill to write new sketches! That's what we'll be doing in this lesson. To start we will venture deep into the Blink sketch, looking at each line and trying to understand what its doing. Then we will start hacking the sketch, and maybe even meet an internationally-famous DJ and design custom hardware for him!
Run an X-Carve CNC Machine Wirelessly with a Raspberry Pi
Use a simple Node.js server on a Raspberry Pi to link your X-Carve to Easel wirelessly.
by Todd Treece
Inventables' web based digital CNC software, Easel, currently requires a constant connection from a Mac or Windows based machine in order to send commands to the X-Carve over a serial port. This tutorial will show you how you can free up your main computer while the X-Carve is running by using a Raspberry Pi as a bridge to wirelessly send commands to the X-Carve's Arduino Uno. We will also use a Powerswitch Tail to automatically control the main power to the X-Carve when Easel launches in your web browser.
