Remote control Sensor?
Hey I am doing A2 level engineering at college and for my coursework i have upgraded my last years project which is a remote control hovercraft i have upgraded my motors and layout etc etc but we require more electronics this year. i an wanting to know how i could possibly mount 2 sensors at the front so that i can make the hovercraft run by itself and if it approaches an object it turns away from it. i would like that to be a sub system itself so i can turn it on and off for when i want to use the remote control. how can i do this? thanks
