50 of the most important Raspberry Pi Sensors and Components

50 Raspberry Pi Sensors and Components.

One of the many advantages of the Raspberry Pi is that it is possible to connect almost all standard Arduino and Raspberry Pi sensors and components to the various GPIOs. Moreover you can evaluate and / or process the values with programs and other software. This accessory can be used in projects such as Smart Home (home automation), robot kits or weather stations, etc.

This article describes and summarizes over 50 of the most important sensors and components for Raspberry Pi’s as well as Arduinos and provides you with a full Raspberry Pi sensor list.

Raspberry Pi Stepper Motor Control with L293D / ULN2003A

Stepper motors are ideal for applications where it is necessary to know the angle of rotation, for example in robotics. Unlike a normal motor, stepper motors can control the steps individually and can therefore detect the exact position.
For easy controlling such a motor, a driver IC like the L293D or the ULN2003 are needed. The use of both drivers is shown in this tutorial.
