Paper 1
Revise: InputsTwo useful approaches are a pressure switch and a force-sensitive resistor, or FSR.
Name the component as well as the input: an LDR senses light, a thermistor senses temperature and an FSR senses applied force.
Distinguish an FSR’s changing resistance from a pressure switch’s open or closed contacts.
