As my old arduino was sold (for wine or for something useful), I decided to do a 100% compatible but without the bugs that I had…

An excellent way to reprogram Arduinos, among others…
Already bought a few months valiant this programmer, It costs about 15 €, Although you can find between 10 e 40, but decided to purchase where trust and, the past two weeks came, everything ok and functional, the first test I did was with my ‘old’ Arduino UNO (We have already dispatched for some time).

Meteorological Station (Arduino ATMEGA328)
June 29th, 2011 by Miguel Ferreira | In: Arduino, Arduino, Blog, Electronics, Programming, projectsSince some time I have been to develop a meteorological station for the Free Flight Club of Caramulo with an Internet connection to update in real time….
This spaghetti of wires is only one Arduino (changed to 20 MHz) with a network card based on chip ENC28J60 (better than Wiz official), is so linked only to tests of UPTIME and reliability. So far has an uptime of about 2 months and, taking into account that my cat engraçou with temperature sensor…
The first version I made this station is based on the Arduino UNO with the official network adapter (The Wiz between 25 e 50 euros) – A huge waste of money, the second is based on the same in the arduino but this time with a much cheaper (between 14 the 30 euros) and witheurosoubt much more reliable
Now, I am trying to remove all of the potential problems that can happen to me – that being said the main source of problems is the own arduino… Result: use the ATMEGA328 for its ease of programming and information quantity, but on a plate made by me, thus reducing costs and making the project a lot more functional.
