• The long leg of LED & Buzzer ➡ GP15 (Pico)
• Short Leg of Led & Buzzer ➡ GND (Pico)
• Brown Wire Pin of trigger push button ➡ GND (Pico)
• Yellow Wire Pin of trigger push button ➡ GP27 (Pico)
• Red Wire Pin of trigger push button ➡ VBUS (Pico)

Now we are using the Thonny Python IDE for giving the instruction to the pi pico, so that when we trigger the push button the desired action can perform

• Download the Thonny Python IDE using this link
  
• Install it in your machine
  

• Download the CircuitPython UF2 by using this link
  
• Push and hold the BOOTSEL button and plug your Pico into the USB port of your computer. Release the BOOTSEL button after your Pico is connected.
  

• Drag and drop the CircuitPython UF2 file onto the RPI-RP2 volume. Your Pico will reboot. You are now running CircuitPython.

Now add the adafruit_circuitpython_hid library for adding the keyboard and mouse capabilities into the pi pico. Download the library by clicking the below button.

• Download the library by clicking this link
• Inside the library folder, copy the lib folder
  

• Now paste this folder into the pi pico volume.
  

Write the below code and save the file with the name of code.py. (If you are saving the file with another name then in that condition you will have to upload the code each time when you plugged the pi pico

        keyboard.release(0x2C)
