Do you need a screen when using Raspberry Pi?

Yes, a screen is necessary when using Raspberry Pi as it allows you to interact with the device and see the output of the programs you run on it.

There are several ways to connect a screen to a Raspberry Pi. You can use a HDMI cable to connect it to a monitor or TV, or you can use a touchscreen display that connects directly to the Raspberry Pi's GPIO pins.

However, it's worth noting that there are some applications where you may not need a screen, such as when using the Raspberry Pi as a server or running headless programs. In such cases, you can access the Raspberry Pi remotely over the network using a tool like SSH (Secure Shell) or VNC (Virtual Network Computing).
