Blindman Traffic Lights (two pins for three lights)
This projects was made to one private-neighborhood.
To meet the regulations, they must provide some safe crossing pathway for childs, adults and blindmans. So I make this project using only two pins for three lights + activation button + night/day detection + sound tic (distinctive for blindmans)
That make some low rate tic noise to allow find the crossing pathway, and a high rate tic noise when crossing is allowed, during night the low rate, becomes lowest to avoid disturbing the sleeping time.
The button also is used in the night, to make shortest the waiting time to light changing.
