Hi,
I salvaged this cool device (contains a serial LED 7 segment display) from garbage and have NO clue what it was. But it is cool, I keep it.
However it worked well as I tested it out of its housing, but now with the long cable I suppose I need to denoise the signal lines.
All what is in the cable is VCC/GND DIN (data), CLK and a Strobe STB directly connected to an Arduinos digital pins. What can I do to denoise the signals?
Thanks,
Carsten
