Stop N Go

Our project is to create an atonomous car that will respond to a stop light. It will see the yellow light, pull up to the light, wait for it to turn off or see the green light and then take off. Can anyone recomend a good photatransistor website that has them in the peak wavelenghts from 550-650 nm. I cant find them anywhere . thanks

Most all transistor photo detectors cover that range, see this URL: **broken link removed**

You need a green filter to select that color.
