Sonic pi is an open-source programming environment designed to explore and teach programming concepts by creating sound production music processes. The Code executed by sonic pi is based on Ruby, which is a beautiful and concise programming language. This means that you can write a lot of code without having to worry too much about syntax and braces-though important for complex programs. 1. Getting Started

If the device is not received, after using VNC login, the display resolution is very small, should be 480p, resulting in a very inconvenient use.By modifying the/boot/config.txt file, the desktop can also be displayed at a set resolution when the monitor is not connected. Here's how:1. Open Config.txt FileMethod One: Use the SD card reader to open the Config.txt file in the boot folder in the Windows environmentMethod Two: After entering the raspberry

of the CPU is detected and written into the system files, and timed refresh. The specific path to this file is/sys/class/thermal/thermal_zone0/temp, which is a read-only file. We only need to access this file to get the current CPU temperature. Viewing through the graphical interface is simple and only provides a way to view it using terminal commands.Enter the following command at the terminal: Cd/sys/class/thermal/thermal_zone0 After entering the directory where the temp file is located, ente
