But one question: isnĀ“t it possible to craete an vga signals with an arduino itself? than it could become an awsome standalone audiovisualizer. Means, just an I-pod a little box wich would be conactable quick everywhere!<br /><br />greetz, DavidDavidnoreply@blogger.comtag:blogger.com,1999:blog-23217409.post-23653502284687332172009-04-04T07:24:00.000+10:302009-04-04T07:24:00.000+10:30hi steven, please check: http://www.youtube.com/wa...hi steven, please check: http://www.youtube.com/watch?v=NfwH35fCY8kSebastian Tomczakhttps://www.blogger.com/profile/12712567577323498804noreply@blogger.comtag:blogger.com,1999:blog-23217409.post-17673204097917766302009-04-03T20:23:00.000+10:302009-04-03T20:23:00.000+10:30i'd love to see a video!i'd love to see a video!stevenhttps://www.blogger.com/profile/14279733499136070645noreply@blogger.comtag:blogger.com,1999:blog-23217409.post-11168054992789020812009-04-02T07:50:00.000+10:302009-04-02T07:50:00.000+10:30h and v sync signals are coming from a laptop. the...h and v sync signals are coming from a laptop. then instead of the RGB signals coming through from the laptop, these lines are controlled by a microcontroller that simply does an analog to digital conversion of an audio signal and sets the RGB lines to bits 4, 5 and 6. This is then repeated without delay. As a result, louder sounds will tend to generate more colours while lower frequency sounds will tend to generate taller bars on the screen. So that's the basic idea, and for the second monitor, it has the same information going to it as the first but the RGB bits are routed differently, hence they are in sync with each other but with different colours.Sebastian Tomczakhttps://www.blogger.com/profile/12712567577323498804noreply@blogger.comtag:blogger.com,1999:blog-23217409.post-69740617023655512282009-04-01T23:13:00.000+10:302009-04-01T23:13:00.000+10:30What's driving the VGA displays?What's driving the VGA displays?Simon Knighthttps://www.blogger.com/profile/06296005980778410544noreply@blogger.com
