With just a few components and the right Python code, the minicomputer becomes an electronics lab. The focus is on electronics. The learning package offers something like a complete small electronics practical.Already experimented today? Whether you use the Raspberry Pi as a full-fledged component tester or as a simple oscilloscope, you will learn how to use the GPIO ports in a practical way. You will take a look behind the scenes and learn how to measure the access time to the ports. For the output of the measurement results the graphical Tkinter library is used. With the knowledge gained, your own projects on the GPIO become child's play.With the right software, you can get a lot out of the system together with the Raspberry Pi 4. This is possible thanks to the freely accessible connections. All projects can be done with the Raspberry Pi 4 but also 2. These are some of the projects you will carry out:Graphical programming with TkinterTransistor switchTransistor.
