3 Stage sequence circuit - looped
You can change the duration of any interval by raising the value of that 100k Ohm / 200k Ohm and the corresponding 22 uF capacitors.
For red, red and yellow, green, green and yellow and back to red there are 4 stages necessary. Workspace is a bit small...But you get the idea.
