movement decision taken upon the light seen by a robot Answered
I'm working on a line follower robot and it has to check traffic lights every estimated distance
and a decision of whether to move or wait is to be taken upon the current state's light of an external traffic signal [ green to move..etc ]
it has to be done without the help of a micro-controller
i couldn't find a color sensor without the usage of MC. however i managed to find a only one color detector using an LDR and a LED with the given color. could this sensor help in my project ?
moreover the robot will have to check two traffic signals at the same time and will move only if one of them is green [ if both are green it will have to stop ]
should i connect Green1 & Green2 states of the two sensors to an XOR gate or there is a more appropriate way ?
