This chip can handle up to 8 individual touch pads, and has a very nice feature that makes it stand out for us: it will light up the 8 onboard LEDs when the matching touch sensor fires to help you debug your sensor setup.\u003c\/p\u003e\n\u003cp\u003eThe CAP1188 has support for both I2C and SPI, so it is easy to use with any microcontroller. If you are using I2C, you can select one of 5 addresses, for a total of 40 capacitive touch pads on one I2C 2-wire bus. Using this chip is a lot easier than doing the capacitive sensing with analogue inputs: it handles all the filtering for you and can be configured for more\/less sensitivity.\u003c\/p\u003e\n\u003cp\u003eComes with a fully assembled board, and a stick of 0.1\" header so you can plug it into a breadboard. For contacts, we suggest using copper foil, then solder a wire that connects from the foil pad to the breakout.\u003c\/p\u003e\n\u003cp\u003eGetting started is a breeze with our Arduino library and tutorial. You'll be up and running in a few minutes, and if you are using another microcontroller, it's easy to port our code.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote\u003c\/strong\u003e: Breadboard, Arduino UNO board and cables are \u003cstrong\u003eNOT \u003c\/strong\u003eincluded\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDimensions: 42mm x 18mm\u003c\/li\u003e\n\u003cli\u003eWeight: 2.5g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eResources\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDownloads and Tutorial\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c!----\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":52217208111392,"sku":"nfy1787257245893","price":4.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0946\/3231\/3120\/files\/cap1188---8-key-capacitive-touch-sensor-breakout---i2c-or-spi_1.jpg?v=1787257250","url":"https:\/\/www.elmwoodbasket.shop\/products\/cap1188-8-key-capacitive-touch-sensor-breakout-i2c-or-spi","provider":"My Store","version":"1.0","type":"link"}
