Arduino Resistive Touchscreen Panel

This video demonstrates how to use a resistive touchscreen panel, as you might normally find on a tablet or touch-enabled PC monitor, used an input to an Arduino.
The Arduino sketch monitors the position of a finger touching the panel and displays that location as an (x,y) co-ordinate. If the touchscreen panel were placed as one of the panels in a glass cabinet, say, this could be used as a way of detecting which object within the cabinet a person was pointing at.

very nice ts video... thanks a lot...:)

Quick question, I have a device that has a small 4 wire resistive touch screen which no longer responds, I have found a replacement 4 wire touch screen, however, the original screen has the lead positioned along the bottom edge on the left hand side corner, the only screen I can find has the lead coming from the bottom right hand side, will this cause the X,Y co-ordinates be different between the 2 screens? I’m not sure if the device has a screen calibration option, there is a mini USB socket on the main board so I’m assuming there is some way to calibrate it using a pc but wouldn’t know where to start with that 😂

Sir, can you make a project where this touch screen would be connected to a esp8266 and a local webpage will be hosted there. In AP mode if anyone connect to the access point created by the ESP8266 and enter the default IP address one blank webpage will open. If user draw something on the touch screen it will show in that webpage.

Is there a place to get these cheaply? Always good for a small project

I got mine for £8.50 on eBay - look for notepad touchscreen spares/repairs

[@TopBanana12]

@@PlayfulTechnology thanks! I'll have to take a look

Could you share the link where you bought the screen? I can’t seem to find a large enough screen

There are plenty of old tablets that could be used as an touch screen on an Arduino project (Something like an HMI). Can you please take some time and open for as this door. They both have USB ports and some boards Bluetooth, so it shouldn't be that hard for a knowledgeable person. Thank you in advance.

smartphones have capacitive touch not resistive
