Digital output problem

Post by Heart » Wed May 11, 2016 5:32 pm

When I use the "glowbug" output (for example, the LEDs light red), then other outputs to a High level is not 5V, but half the supply voltage (2.51V). If I set the color black (all leds off), then all (other) outputs level is okay. Why? :o

The problem is solved. I made a mistake. 30 units have already led you to be the serial data line is a 470 ohm resistor + 2 diodes and a buffer capacitor. Sorry!
