1. Copy full-screen.sh intothrough the homeUSB foldercable either to a computer or a phone charger. If you are going for a wireless design, you can use batteries as well. This tutorial will demonstrate how to power a Pico with a 9V battery or 3 AA batteries.

   Raspberry Pi Pico pinout

   You have to find out the pinout of the pimodel user,you are using. The pins you are looking for are VSYS and runGND. In this tutorial, a Pico W is used.

   Raspberry Pi Pico's Power Need

   VSYS (PIN 39): Pin for main system input voltage. The input voltage can vary between 1.8V to 5.5V. This voltage is used by the followingonboard command:SMPS /home/pi/full-screen.shto generate 3.3V to power the RP2040 microcontroller and GPIOs.

   Why these parts are needed

   • Switch: When we are using batteries to power the microcontroller, a switch is preferred. Some battery holder has a built-in switch which will be more convenient for you. With a switch, you can turn off the Pico when not in use and not drain the battery.

sudoLM7805: chmodThe LM7805 is a popular voltage regulator integrated circuit (IC). It is a positive voltage regulator that provides a stable and fixed output voltage of +x5 full-screen.shvolts. It is widely used in electronic circuits to regulate the voltage and ensure a consistent and reliable power supply. It can accept an input voltage in the range of 7V to 35V, depending on the specific model, so you will need this when you are using a power supply with a voltage higher than 5V.

Diode: - A diode is a semiconductor device that allows current to flow in one direction while blocking it in the opposite direction. In other words, it acts as a one-way valve for electric current. We need a diode for safety to prevent one power source from back-feeding the other. Raspberry Pi can have two power sources at the same time and there is a risk of unwanted power flow between the two power sources. Schottky diode is preferred for its low voltage drop, but any others should work with a bit of voltage drop around 0.2-0.6V.

2. Create a folder called autorun inside the .config folder of the home folder of the pi user: /home/pi/.config/autorun/kiosk.desktop

cd /home/pi/.config mkdir autorun

kiosk.desktop

3. Reboot the Raspberry Pi.
