Capacitive touch sensing works by detecting when a person (or animal) has touched one of the sensor electrodes. Capacitive touch sensing is 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 shield allows you to create electronics that can react to human touch, with up to 12 individual sensors.\u003c\/p\u003e\n\u003cp\u003eThe shield has 12 'figure 8' holes in it that can be gripped onto with alligator clip cables. Attach one side of the clip to the shield and the other side to something electrically conductive (like metal) or full of water (like vegetables or fruit!) Then start up our handy Arduino library 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. Works great with any Arduino as it only uses the I2C pins (SCL \u0026amp; SDA).\u003c\/p\u003e\n\u003cp\u003eIt uses the same chip as our MPR121 12-Key Capacitive Touch Sensor Breakout so you can duplicate the library and code! We have examples for reading touches. Using an Arduino Leonardo and a little bit of creativity you can use it to turn touches into keyboard KeyUp\/KeyDown presses (so you can make a veggie keyboard) or pair it with our Music Maker shield to create an audio player that will play a sound per sensor (fruit drums!)\u003c\/p\u003e\n\u003cp\u003eEach order comes with a Capacitive Touch Shield and a stick of 36-pin headers. You'll need to do some light through-hole soldering to attach the headers onto the shield 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 TFT display is big (2.8\" diagonal) bright (4 white-LED backlight) and colorful (18-bit 262,000 different shades)! 240x320 pixels with individual pixel control. It has way more resolution than a black and white 128x64 display. As a bonus, this display has a capacitive touchscreen attached to it already, so you can detect finger presses anywhere on the screen.\u003cbr\u003e\u003cbr\u003eThis shield is the capacitive version as opposed to the resistive touchscreen we also sell. This touchscreen doesn't require pressing down on the screen with a stylus, and has a nice glossy glass cover. It is a single-touch display.\u003cbr\u003e\u003cbr\u003eThis shield uses SPI for the display and SD card and is easier to use with UNO, Mega \u0026amp; Leonardo Arduino's. The capacitive touchscreen controller uses I2C but you can share the I2C bus with other I2C devices.\u003cbr\u003e\u003cbr\u003eThe shield is fully assembled, tested and ready to go. No wiring, no soldering! Simply plug it in and load up our library - you'll have it running in under 10 minutes! Works best with any classic Arduino (UNO\/Duemilanove\/Diecimila). Solder three jumpers and you can use it at full speed on a Leonardo or Mega as well.\u003cbr\u003e\u003cbr\u003eThis display shield has a controller built into it with RAM buffering, so that almost no work is done by the microcontroller. This shield needs fewer pins than our v1 shield, so you can connect more sensors, buttons and LEDs: 5 SPI pins for the display, 2 shared I2C pins for the touchscreen controller and another pin for uSD card if you want to read images off of it.\u003cbr\u003e\u003cbr\u003eOf course, we wouldn't just leave you with a datasheet and a \"good luck!\" - we've written a full open source graphics library that can draw pixels, lines, rectangles, circles and text. We also have a touch screen library that detects x \u0026amp; y location and example code to demonstrate all of it.
