Very simple Arduino code just to check out the board ... You can see how easy it is to use the digital I/O and the serial port .

Arduino Tone Experiment
Tonight's project , a variation on the morse code stuff I was doing a while back.
They are sideways . They are a little slanted. But what the heck .
I can't "read" Morse Code naturally. I've seen those with a real knack for it though.
But I can read.
Could I cobble something up an hour or so to "print" an audio signal onto a computer screen ?
Here is a screen shot of some letter As .
You need to use your imagination a bit.
More to follow .

Pic of the Day
Today's pic of the day is the Arduino Due I grafted on to the old Radio Shack Sensor Lab.
It doesn't look like much , but it should get my feet wet and help convince me to get an Arduino Esplora .

Friday Fun
After dropping my son off at school, I had breakfast with the gang from the Broken Arrow Amateur Radio Club at the Kenosha Cafe.
Guy had my day planned and sent me off to Ray's to work on his DVAP and Raspberry Pi.
The DVAP is a low-powered RF to Internet gateway for D-STAR traffic.
It works. Didn't take too long to make up a Raspberry Pi SD Card, get the Pi booted and set up with the DVAPTool program and then we were chatting to folks on the 030C reflector with his Icom ID-51 walkie talkie and the DVAP.
More to follow on this interesting aspect of ham radio. At this point, in a nutshell, suffice it to say, the audio is good (digital) there is a low-rate data sub channel and almost all D-STAR repeaters pipe their audio to the Internet. This makes it easy to make up "conference calls" of several users and repeaters.
