The circuit is a homemade ISP using an ATmega8 with USB communication and software that allows to program AVR microcontrollers more (ATmega, ATiny) to be used as Arduino, an eco-mode. It is good to always have a backup programmer as a plan B The schematic and firmware can be seen here. Below are pictures of the experience. […]
ATMEGA328 … parte 2
Today I decided I had time, and after reading something more (http://mightyohm.com/blog/products/hv-rescue-shield-2-x/) did on Board of experiences to see if my beautiful atmega was returning to hear me….
Atmega 328P-PU – DEAF!
Gave me the ' spoil’ an ATMEGA328P-PU for having cheated on ' fuses '… But no remedy 🙂
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. […]
My Homemade Arduino
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…
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 […]
