Homemade Arduino with ENC28J60

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 […]

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 […]

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 […]

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 […]
