RGB Spinning Display

at 5:48 pm. Filed under Complex Hacks, Cool Gadgets, Electronic Hacks


Brad from Brads Electronic Projects shows us how to make 8 RGB LEDs create a large circular display. He uses a spread sheet to create the HEX data that the PIC microcontroller will be using to turn on the RGB LEDs to make the system display what you would like but the display data is stored on an EPROM to allow for large moving displays. Reminds me a bit of my POV Display that I made many moons ago, only thing is that Brad’s is about 100 times better. ūüôĀ

    […] Brad @ bradsprojects.com shows us how to use 8 RGB LEDs to make a POV display. To produce the display image hex code he uses an excel spreadsheet and then he programs the HEX code to the PIC. The¬†display data is stored on an EPROM that allows to store large messages. Check the video above.¬† [via] […]
