# Touch Element basic example (EVENT)
# Touch Element matrix example
(See the README.md file in the upper level 'examples' directory for more information about examples.)
This example demonstrates how to use the Touch Element library of capacitive touch sensor and set up touch matrix.
## How to use example
### Hardware Required
* A development board with ESP32-S2 or ESP32-S3 chip
* A touch extension board like [esp32-s2-touch-devkit-1](https://docs.espressif.com/projects/espressif-esp-dev-kits/en/latest/esp32s2/esp32-s2-touch-devkit-1/user_guide.html)
### Configure the project
* Set the target of the build (where `{IDF_TARGET}` stands for the target chip such as `esp32` or `esp32s2`).
* Run `menuconfig` to select a dispatch method for the example.
* Set the target of the build by following command, where TARGET can be `esp32s2` or `esp32s3`.
```
idf.py set-target TARGET
```
* Run `idf.py menuconfig` to select a dispatch method for the example.
### Build and Flash
Build the project and flash it to the target board, then run monitor tool to view serial output:
