ESP32 steuert Roboterauto : Open-Source-Code mit Arduino IDE und PlatformIO | Autonomes Fahren: GPS, Accelerometer, Gyroskop

Microcontrollers like the Arduino and single-board computers like the Raspberry Pi have become popular components. Third in the group is the ESP32 from Espressif. Microcontrollers of this series are characterized by a large number of implemented functions that are only possible with additional hardware in a conventional Arduino with an Atmel AVR microcontroller. Prominent examples here are the WiFi and Bluetooth functionalities. Compared to a Raspberry Pi, they are characterized by a significantly lower price.

General information for realizing a robot car project with the ESP32 is easy to find. However, these are often only statements on a partial aspect, without coordination in terms of content or function. Not only is obtaining the required information tedious and time-consuming, it can also be extremely error-prone.

The aim of this book is to fill this gap. It goes into the different possibilities of a chassis, conveys the necessary knowledge and leads step by step from a simple engine control to a complex sensor and voice-controlled robot car. Hacks around GPS and a PlayStation 3 round things off.
