I am done with testing the sound function on the ATTiny without the tone command (as we know it’s not working with the ATTiny). Thanks to this website http://web.media.mit.edu/~leah/LilyPad/07_sound.html I could make my AtTiny playing a “do re me fa so la ti do” scale
Now comes the tricky part. How the hell can I measure the frequency and the tone lenght of Artoo’s beep’s? Any help there?
I am planning to use one of the motor pins for that, maybe the right motor reverse pin. It should not move the motor by playing the tone sequence i guess.
How about to use the reset pin for that? I heard that it can be used as a weak I/O pin but have to take care that you not pull it to ground.
I think you’re going to need some sort of audio spectrum analyzer (something like this perhaps) and samples of R2 boops and beeps to translate. You seem to have already found the other piece of the conversion puzzle.
OMG, that’s a bit complicate for this tiny project I am going with one of those sound modules and try to hack it to upload/record my own sound there. Those MP3 board you linked to is too big for that little can.
It took me a while to put all into the little can…you know the size of my hands and so I went to bed at 2:30am. Could not stop and wait a day more since I promised to show it off today ;-)))
yes that’s the plan Chopsticks Junior is going to an exhibition in the end of April and this little one will accompany me to the Great Chinese Wall, Honkong and Sanya Beach for the next 2 weeks. Will try to upload videos from there.
I’d never really considered the tiny85 and I’d never considered making a super mini sound playback module but I found the Simple SD Audio Player that uses a tiny85 as the controller. I was impressed! I think I can cram one into the R2 tin I bought if it’s done correctly.
The LU2MI2 project is underway! Thanks for the impetus :)
