A flex sensor is an affordable and user-friendly variable resistor specifically designed to measure the degree of deflection it undergoes when bent. Its resistance is at its lowest when it is in a flat position on a surface. As we gradually bend the sensor, its resistance increases, reaching its highest point when it is bent at a 90-degree angle.
Flex sensors have gained popularity due to their versatility and are utilized in various applications, such as game controllers, data gloves, motion trackers, and even in biomedical devices for capturing both static and dynamic postures. In today’s project, we will delve into the intricacies of flex sensors, understanding their functioning, and exploring methods to connect them with an Arduino.
