The Raspberry Pi is a small computer without housing that can be expanded with many add-ons. The board is about the same size as a credit card. All of the electronic components are on the small board. The minicomputer was developed for demonstration and learning purposes. However, it is also useful for a variety of professional applications. The required software runs in Linux.

How can I use my Raspberry Pi with fischertechnik motors and sensors?
The Raspberry Pi has GPIO-Pins (GeneralPurposeInputOutput). You can use these in conjunction with a voltage divider to query buttons or light barriers, however an additional ADC (analogue-to-digital converter) is best for analogue sensors. The same applies to motors: a motor shield is required for activation. Ideally, this will provide a 9V PWM.
Possible setup: Raspberry Pi + Adafruit DC and StepperMotorHAT for Raspberry Pi + Adafruit4-ChannelADCBreakouts + fischertechnik motors/sensors/construction kits
