Capacitive touch sensing works by detecting when a person (or animal) has touched one of the sensor electrodes. Capacitive touch sensing used for stuff like touch-reactive tablets and phones, as well as control panels for appliances, which is where you may have used it before. This HAT allows you to create electronics that can react to human touch, with up to 12 individual sensors.\u003c\/p\u003e\n\u003cp\u003eThe HAT has 12 'figure 8' holes in it that can be gripped onto with alligator clip cables. Attach one side of the clip to the HAT and the other side to something electrically conductive (like metal) or full of water (like vegetables or fruit!) Then start up our handy Python library code to detect when the object is touched. That's pretty much it, very easy! For advanced users, you can also solder to a pad to make a slimmer \u0026amp; more permanent connection.\u003c\/p\u003e\n\u003cp\u003eWorks great with any Raspberry Pi that has a 2 x 20 connector This HAT can be used with Model A or Model B but requires the purchase\/soldering of an extra-tall 2 x 13 header instead of the 2 x 20 included.\u003c\/p\u003e\n\u003cp\u003eCheck out the MPR121 sensor guide for CircuitPython and Python usage!. We have examples for reading touches, turning touches into keyboard KeyUp\/KeyDown presses (so you can make a veggie keyboard) as well as an audio player that will play a sound per sensor (fruit drums!)\u003c\/p\u003e\n\u003cp\u003eEach order comes with a Capacitive Touch HAT and a 2x20 socket header. You'll need to do some light through-hole soldering to attach the headers onto the HAT circuit board, but it's easy to do with basic soldering tools like a soldering iron and rosin core electronics solder. You'll also likely want to pick up a 12-pack of alligator clips!\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePlease note! This kit does NOT come with Raspberry Pi, alligator clips, speakers, or delicious fruit!\u003c\/strong\u003e However, we do have all of those in the store. Well, all except fruit - despite being called Adafruit, we do not actually sell fruit. \u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eRevision History:\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAs of July 10, 2024\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003e– we've updated this PCB with Adafruit Pinguin to make a lovely and legible silkscreen - you may get the new PCB or the older version with vector fonts - both are identical other than the fancy silkscreen.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e57mm x 65mm x 3mm\u003c\/li\u003e\n\u003cli\u003eWeight: 10g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eResources\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eEagleCAD PCB files\u003c\/li\u003e\n\u003cli\u003eAdafruit Fritzing Library\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c!----\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":44930601779289,"sku":"wie1789671262498","price":14.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0736\/5289\/5833\/files\/adafruit-capacitive-touch-hat-for-raspberry-pi---mini-kit---mpr121_1.jpg?v=1789671266","url":"https:\/\/gymflexfit.shop\/products\/adafruit-capacitive-touch-hat-for-raspberry-pi-mini-kit-mpr121","provider":"My Store","version":"1.0","type":"link"}
