[TriEmbed] CD4027 Flip Flop & My Traffic Light Project

[Grawburg]

If I understand the schematic and datasheet correctly for the CD4027 JK flip flop, and a suggested circuit, I can. . . 1. Operate with 3.3VDC 
2. In the drawing the pushbutton controls an LED. I can make this one of the inputs of my MCP23017 instead.
