hi, im new to this and electronics so sorry if i get the wrong page, i am a college student and i study physics maths further maths and chemistry (ie not electronics) but i am doing a challenge for the silver crest award and our project is to make a car park barrier lift when a car distorts the electromagnetic field.....
anywho we have made the breadboard up to the point of where we need the motor to change but we have a speaker set in at the moment and as the magnetic field changes the frequancy changes.... so i was wondering how we make the arm on the barrier lift when the frequancy changes, something like i would call a frequancy dependant resistor? :s hope this is enough info please help! we are a team of 4 and are stuck!
Thanks Andy
