ATMEGA328

True low cost arduino

With half a dozen euros is an arduino, stable and functional. Bill of material: – 1 ATMEGA328p – 1 16 MHz Xtal – 1 USB2Serie Some rigid wires A white plate of experiments and everything is done 🙂 I haven't figured out the exact amount this cost me yet, but I plan to put all these pieces together […]

In Barometric Sensor Ethershield

This is a preliminary test of a barometric sensor connected to an Arduino board with homemade ENC28j60, that allows you to read the atmospheric pressure in real time using I2C in PA (Pascal) from the point where. It also makes reading of temperature. Is a strong candidate to get in several projects intended for meteorology home. […]

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 […]

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 […]
