Chapter 4 Microcontroller: Arduino
The microcontrollers we use in this book come are all supported by the Arduino integrated development environment (IDE), which provides an easy-to-use programming environment that allows us to quickly start developing software. There are limitations, but it is a wonderful system to start learning about microcontrollers.
4.1 HARDWARE
The original Arduinos are based on Atmel microcontrollers and we mostly discuss the Arduino UNO. Support for additional families of controllers, based on ESP8266 and ESP32 microcontrollers with built-in WLAN support was later integrated into the Arduino IDE. These controllers can be therefore programmed in much the same way as UNOs. But let us start ...
