ESP32 Codelock with Touch

A lot of customers asked us for a very simple code example for ArduiTouch to test their work and also as starting point for own developments. This very simple codelock will demonstrate the basic functions of Arduitouch ESP without any bells and whistles.

Assembly:

Please follow for the assembly of the ArduiTouch ESP our construction manual for Arduitouch ESP.

Installation of additional libraries:

Install the following libraries through Arduino Library Manager

• Adafruit GFX Library
• Adafruit ILI9341 Library
• XPT2046_Touchscreen by Paul Stoffregen

You can download the library also directly as ZIP file and uncompress the folder under yourarduinosketchfolder/libraries/

After installing the Adafruit libraries, please restart the Arduino IDE.

Custom settings:

In the source code you can set the code number to an value of your choice:

#define codenum 42

42 is the answer for everything, but you can change this to any number between 0 and 999999.

Run the demo:

Please open this sample in the Arduino IDE. After compilation and upload you will see the keypad. Now you can enter a code number and confirm with „OK“ button.
