Flex Sensor 4.5 Inch Mq2 It lacks only a DCA simple flex sensor 4. 5 inch in length. As the sensor is flexed, the resistance across the sensor increases. Patented technology by Spectra Symbol they claim these sensors were used in the original Nintendo Power Glove. I love the Nintendo Power Glove. Its so bad! The resistance of the flex sensor changes when the metal pads are on the outside of the bend (text on the inside of the bend). The connector is 0. 1" spaced and breadboard friendly.
