To Build the Code 

To create a Scratch program for Raspberry Pi, begin by powering up the Raspberry Pi 5 and launching Scratch 3. Next, incorporate the Raspberry Pi GPIO extension. The coding process is straightforward, utilizing "IF" and "ELSE" logic. When the Maker Line GPIO pin is activated, the Scratch code employs "IF, ELSE" logic to determine the GPIO pin to activate for the Maker Drive.

To power the Raspberry Pi 5, connect a pair of 3.7V 2000mAH Li-Ion batteries to the Maker Drive, then to the Raspberry Pi 5, and finally to the Maker Line.

Then Connect the Rasspberry PI 5 in Headless Mode by using VNC.
