Flex sensors are great for telling how bent something is in a project, but we've been running into issues with durability when using them in wearable applications like gloves. The Qwiic Flex Glove Controller isolates the weak point to allow for more permanent flex sensor applications. The board has an onboard ADS1015 ADC to I2C so we can get a whole bunch of analog inputs without touching our microcontroller's ADC pins.

In this hookup guide, we'll figure out how to pull values from our fingers as well as calibrate the sensor for our range of motion. We'll also cover recommended placement and installation to implement these into gloves.

Required Materials

To get started, you'll need a microcontroller to, well, control everything.

If you don't have a sewing needle, we'd recommend grabbing one if you're trying to add these flex sensors to some gloves.
