Dear gentleman
Thank you so much for all the information.
Bobby Ogage I have been talking to Dale H via e-mail. Here is the one who gave me the information on the wig wag circuit. But I still thank you for your time and look forward on your advise.
John I know I always can count on you to whip out scheme in no time, if you do not have we know we are all in trouble. After studying it I have some question in regards to the values of the ohms and 12 VDC power supply.
rtr12 Wow that is a lot of information to study, thanks I will look it over. I like your Arduino Traffic Signals layout. Let study that as well. Thanks for the links for the electronics.
