Resistive touch screens are incredibly popular as overlays to TFT and LCD displays. This breakout board features the TSC2046, which has an easy-to-use SPI interface available to read the incoming data from the touch screen. There is also an interrupt pin that you can use to indicate when a touch has been detected to your microcontroller. It can be powered from 3-5V, so it’s safe to use with 3V or 5V logic. It’s a nicely designed chip and has very stable precise readings.
The Adafruit TSC2046 breakout guide has everything you need to get started with using the breakout. There’s pages for overview, pinouts, Arduino and resources for download.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
