Product Features Capacitive touch sensor Requires soldering pin product description Use this easy-to-use, 8-channel capacitive touch sensor splice board to add a host of touch sensors to your next microcontroller project, starring the CAP1188. The chip can handle up to eight separate touch pads and has very good features to make it stand out: When a matching touch sensor is triggered, it will light eight onboard LEDs to help you tune the sensor settings. The CAP1188 supports both I2C and SPI, making it easy to use with any microcontroller. If you are using I2C, you can choose one of five addresses and have a total of 40 capacitive touch pads on an I2C 2-wire bus. Using this chip is much easier than using analog inputs for capacitive sensing: it handles all of the filtering for you and allows you to configure more / less sensitivity. Equipped with a fully assembled circuit board and a 0.1-inch plug to insert it into the breadboard. For contacts, we recommend using copper foil and then soldering the wire from the foil to the split wire. Getting started with Adafruits Arduino libraries and tutorials is a breeze. You will be up and running in minutes and easily porting our code if you are using another microcontroller.
