Connecting a BR-355 GPS receiver to Arduino with UART (TTL serial)

One of the reasons that I started with Arduino was that I had an idea about making something similar to the ScanGauge II that I read about at ThinkGeek. Reading electronics catalogs I realized that there were lots and lots of different cool sensors that I could integrate into such a design, and after a [...]

I wrote earlier about AVRISP MkII, permission problems with avrdude and Ubuntu 9.04 amd64 and have learned a bit more since then. When surfing and searching for something Arduino related I found the Arduino Playground page on udev with a link to this post in the Arduino Forum. The forum post suggests the use of [...]

Inspired by Todd’s minimal Arduino on a breadboard I made a slightly more advanced version on a protoboard piece. I wanted an ISP port for bootloader upload, an FTDI port for communication, auto reset for program upload from Arduino IDE, and a LED to see that it is working properly.
The end result turned out something [...]

Update 2009-07-21: improved rules in this post.
I bought an Atmel AVRISP MkII today, happily plugged it in hoping that my Linux box running Ubuntu 9.04 amd64 would accept it, but I was wrong.
I was told: avrdude: usb_open(): cannot read serial number “error sending control message: Operation not permitted”
After google:ing a bit I found this old [...]

JArduino? What’s that? Yet another Arduino clone?
No, I am sorry but it is not quite that easy. My name is Johan Adler, my initials are JA, I am (quite) new to electronics and microcontrollers and my first MCU contact was with the Arduino (2k9, but in Italian, however that is supposed to be spelled/pronounced).
I will [...]
