Hi iam looking for help with a college project i am doing, it is for sensing forces but the forces are only small. I am using a material called QTC( which changes from an insulator to a conductor when a force is applied to it). I am not doing electronics at college, so i only have a limited knowledge of electronics and circuits. How would i design a circuit that would switch on an LED at a certain predetermined force, then if the force is too high it would then switch on alternate LED. if this sounds at all possible could somebody suggest a circuit to use, as i have said i am a novice when it comes to electronics. I have come across schmitt triggers but i do not know how they work. thank you in advance.
