Want to poke at your projects? This resistive touch screen can be used with a stylus or fingertip and is easy to use with a microcontroller. You can put it over a paper overlay for a touch control panel or attach it to an LCD to DIY a touch-activated display.

  • 2.2" x 2.75" (55mm x 70mm) overall dimensions, 1.5mm thick
  • 3.2" diagonal active area, 80mm
  • 600 ohms across X pins, 300 ohms across Y pins
  • 4 wire resistive display, on a 0.5mm FPC connector
  • Use any microcontroller with 2 digital pins and two analog input pins
  • Adhesive backing, it fits onto Adafruit's ST7565 LCD (not as well on a KS0108 LCD, its a little too small)

The connector is very fine so they suggests using Adafruit's touch screen breakout board to make it easier to connect.

Adafruit  doesn't have a detailed tutorial yet but Adafruit  does have great example Arduino library code that shows how to get readings, debounce, and read the pressure (so you can detect when its being touched and how hard) The code is not complex and is easily ported to other microcontrollers.

To understand how touchscreens work, and the techniques used to read from them, Adafruit suggests this great app note
