Arduino micro, HR911105A ethernet module, DHT11 temp/humidity analog to digital sensor, a lcd module I got out of a security system, and a bunch of random resistors and diodes. All stuff I had on hand minus the ethernet module. Some custom code, started with the arduino temp sensor example and added to it. The next step is to make a handfull in different locations on my property and pull the data to my server in a textfile and graph temperature differentials using MRTG. The micro-climates on my property are really drastic and I have always wanted to have a visual graph for comparison. Could easily turn one into a full weather station as well I suppose.
Have you played with cacti? I think that would be a better solution for you than MRTG because it can capture damn near any data and display in a graph or just log it for you. It has a pretty steep learning curve, but VERY powerful.
Have never played with that board. Damn! It's really small! What OS / version you using? I've been doing a lot with RPIs and found dietpie to be the meanest / leanest headless distro out there. Worth a look.
There is no OS, you just write a loop of code, flash it, and it runs. Arduino micros are really handy and you can get a 10 pack for like 15 bucks. Also if you are doing anything with pulse width modulation they can't be beat for the price.
Really?!? Wow! I had no idea! What kind of code we talking? Programming or just like shell script level stuff?
I have to admit that I didn't really know about pulse width modulation so did some reading. Another mind blowing thing. So THAT'S how voltage regulators work! Cool shit man! Thanks for sharing this!
I actually do a lot with modulation, but more in the RF realm and some fiber optic. Not sure yet how / if this could apply or fit in.
