Got an IR-receiver from my local electronic-store (see attached pic). Itīs adjustable that it fitīs to the frequency of the roverīs "laser". Now I can shoot on the receiver and turn on and off a light. On the integrated cirucuit there is a relais, too. So in future I can connect maybe some sound or something else.
My game-idea is to to get 4 receivers more and place them on a terrain. Then the time-trial begins and you have to shoot all 5 receivers.
Got an IR-light barrier for time-measuring, too. Havenīt built it yet, but maybe tomorrow.
