Walk/Don't Walk Sign
A working "Walk/Don't Walk" sign for decorative purposes. You can use colored or clear LEDs and opaque or colored gel sheets. I used 5mm and 10mm LEDs and included a file if you wish to use all 5mm LEDs. There is a schematic for reference use only. The circuit will switch back and forth about every 5 seconds. Be sure to use proper sized components and never leave unattended.
