Bildr is a self-described "community of makers, artists, designers, and builders focused on simplifying the world of electronics DIY by modularizing information. Instead of showcasing users’ projects, we offer bite-size, easy-to-follow articles that help you hit the ground running." In short, Bildr is awesome.
One thing that they have been working on is offering tutorials for SparkFun products. Excellent! Adam Meyer, founder of Bildr, started by making a wish list (you know we have wish lists, right?) of all the parts he wanted to do a tutorial for and has been working on creating short-and-sweet tutorials on using each one.
The work they have come up with is outstanding! Check out these tutorials on the MPR21 Capacitive Touch Sensor, the 12 Button Keypad, the ADXL335 Accelerometer, and the Series 1 XBee. There are more tutorials going up almost every day (how do you do it, Adam?!) so keep an eye on the Bildr site for more to come. Outstanding work!
