After I complain of my Arduino Duemilenove due to lack of current to power other devices, I decided to build my own in perforated plate, with a 20 MHz crystal, an LM317 1A and a bus to connect ENC28J60. The part belonging to the Arduino occupies as much or less than the original PCB. Below is the part of the Arduino to function in full, with […]
Electronics (Brazilian Portuguese) or electronic (European Portuguese) (WHEN 1990: Electronics or electronics) is the science that studies how to control electrical energy by electric means that the electrons have key role.

Nokia LCD PIC18F2520
USBtinyISP AVR Atmel
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 (that already […]
Meteorological Station (Arduino ATMEGA328)
For some time I have been developing a weather station for the Clube de Voo Livre do Caramulo with 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 the ENC28J60 chip (better than Wiz official), it is like this […]
Pinguino Project test
Created from the first draft PIC18F4520 Microchip (MultiEth), was changed to be compatible with the PIC18F4550 pinguino minimum.
Arduino DS18B20 1Wire
The idea arose as a means to verify that the temperature of a room was correct before a Mercury thermometer. Arranged an alphanumeric LCD 20×4 characters, a damaged FAX , but luckily the LCD was OK and there were some samples of 1Wire temperature sensors. The objective would therefore be to visualize temperature information […]
Arduino na TV
In General, When we want to display information from the Arduino, such as a temperature sensor, We usually use a serial Terminal, because of the ease in obtaining this. Another way to view this, home with something more, It would be with the LCD, but are somewhat expensive. Then with some research, faced with this site, allowing to display information in a […]
My experience with the Arduino
I'll talk a little about my experience with the arduino..
Liquiduino Shield for Arduino
Here's a shield called Liquiduino, to monitor liquid levels, using sensors (buoys) resistive bridges in order of 0 the 220 Ohms. Has an input and an output event for interaction. The prototype is as follows: It also has a RTC and an EEPROM to register for timed events of variations resulting from the measurement of liquids. It is still about […]
