    Nice project.
    I am _so_ going to build something this year ๐Ÿ™‚
    Last year I made the red board here but it’s not the same as proper lights!

      That’s a nice board , what’s it do ? what’s the processor on it ?

      • John Burton says:

        it’s a xilinx XC2C64A on the red board. It’s not a processor, it’s a CPLD (like a small FPGA). The other board is and only being used to generate a 1HZ clock signal.

        I mostly made the red board to see if I could sucessfully design and a PCB manufactured and solder bigger surface mount chips. Turns out I can ๐Ÿ™‚

        I was going to go on to make something much more impressive but have so little free time and energy after work ๐Ÿ™

    Do you drive the R G B leds separately but all of each colour together? So just 3 outputs?

    • Chipz0r says:

      Yes driving all 3 separately using the PWM outputs on the Arduino

      • John Burton says:

        I must look at driving something bigger than a surface mount LED one day ๐Ÿ™‚

      • John Burton says:

        How many volts and amps are they switching? I guess with pwm they are either on or off so don’t get hot…

        • Chipz0r says:

          The ribbon runs off 12v. when the whole ribbon is lit , white , all 3 leds on it draw’s nearly 3 amps and if left coiled up would get very hot . PWM is so the colours can be faded .
