 In this tutorial, we will learn how to turn on the blue pixel onboard the Arduino® Nano RP2040 Connect board, from another board. For this, we will need two BLE compatible boards, such as the Nano RP2040 Connect board, where we will use the [ArduinoBLE](https://www.arduino.cc/en/Reference/ArduinoLSM6DS3) library to make the connection.

 Now, if we press the button on the peripheral device, we can see two things change on the **central device.** The blue LED will turn ON, and the Serial Monitor will instead print **"ON"**. We can now turn ON or OFF the LED, through pushing the same button.
