The (albeit crooked) image above is a basic environmental monitor I built for the server rack that I keep my house’s servers in. This project features network connectivity via an Arduino Ethernet shield, an HTF3223 humidity sensor, a TMP36 temperature sensor and a Sparkfun serial LCD for a decent monitoring station that is self-reliant. Read more for build details and the code to get it all working. (continue reading…)
We managed to unearth an old IBM RS/6000 server at work and decided that since the machine didn’t work, it was time for it to go away. Right off the bat, one of the things I noticed about this machine was that it had a diagnostic LCD panel in the bezel presumably for showing POST error codes and warnings. Since the machine was going to the scrap heap, I decided to relieve it of the LCD and managed to get it to work on an Arduino with minimal effort. Read on for pictures and a wiring pinout.
Have a giant Arduino powered killbot, but can’t fancy being right next to it when you unleash it on the unsuspecting populace? Want to change the mood-lights in your dorm without having to get up off the couch? Why not use IR remote controls to do the walking for you? In this article, I will be covering how to use the IRremote Library written by Ken Shirriff for the Arduino to control a seven segment display as a proof of concept. Killbot not included.
After reading this post on Hack-a-day, I went to the local MicroCenter to see what all they had to offer in a brick-and-mortar store. I remember when Parallax and RadioShack had joined together and while the new availability had made it easier to get started with microcontrollers, the most common expression recalled is one of sadness at the general disarray of the parts cabinets. Thankfully Microcenter seems to have done Sparkfun right. Read on for my initial impressions of Microcenter’s offerings and a full review of my first Arduino kit, the Sparkfun Inventor’s Kit.
