MOD-LCD3310 uses UEXT connector found from almost every Olimex board. In case you don't have one, you can ...

I finally managed to find time to create AVR-Ada RPMs for Fedora. The packages are available for Fedora 17 and 18 on i386 and x86_64 architectures.

To install them you need to create file /etc/yum.repos.d/fedora-adalanguage.repo with contents:

Required parts:

• Arduino UNO or Duemilanove
• DS18B20 temperature sensor
• Some jumper wires
• About 5K ohm resistor (4.7Kohm or 4.99Kohm is ok)

I had a couple of extra DS18B20 temperature sensors lying around, so I was interested in communicating with them using Arduino.

DS18B20 uses 1-wire protocol for communication ...

Arduino Due is another Arduino board, but with Atmel ARM processor instead of AVR. I have had Due for a while, but flashing it on Linux had not been working. However, now I managed to flash simple blink app (written in C++) on Linux using bossac:
