Pathway: Observing the World Around You

Can your circuit detect movement to run a motor? Yes! Use a Flex Sensor! The flex sensor uses carbon on a strip of plastic to act like a variable resistor but instead of changing the resistance by turning a know, you change it by flexing, or bending the sensor!
