My Homemade Arduino

September 16th, 2011 by Miguel Ferreira | In: Arduino, ATMEGA, ATMEL, Blog

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 and 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, projects

Since 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….

Arduino + ENC28J60 - Estação Meteo de testesThis 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 and 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 without doubt 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.
