Tone music surprises

Hey all! It's almost Christmas and time for the traditional carols. I've found a 8Ω loudspeaker from an old PC and I went through a classic Arduino Sketch for beginners. I've optimized it a little bit. Moreover, I've translated into French/Italian the notes and introduced standardized length for durations and the possibility to add pauses.

The mini IR remote control

In fact, this is not exactly the IR remote I have (see this post) but it has the same overall structure and number of buttons so I suspect that it comes from the same producer as mine and its codes are the same.

Indeed, this was the best photo I could find over the internet and that's the main reason for this picture here. Since I absolutely wanted to use the sensor shield (see this post), I mounted the sensor shield over the Arduino board and wired the IR receiver to the row containing digital pin 3 (right central part of the sensor shield). Following this excellent tutorial from Ladyada website I could decode all the signals sent by the remote control. You can find it on Github here. In a next post I will add some test program, in the meanwhile you can use the one provided by LadyAda tutorial.

Enjoy!

IR remote control

Just received! A new nice module for Arduino. This an IR remote control module. As usual I rushed to the web page of the seller looking for informations and test programs. 

This time informations are terse. It says that I bought a 38KHz IR receiver module. The pin out is as follows


Black wire = GND
Red wire = +5V
Green wire = data
