ESP32 / ESP8266 Arduino: Printing numbers to serial in different bases

In this tutorial, we will check how we can print numbers to the serial port using different bases, more specifically in binary, octal and hexadecimal. The tests on the ESP32 were performed using a DFRobot’s ESP-WROOM-32 device integrated in a ESP32 FireBeetle board. The tests on the ESP8266 were performed on a DFRobot’s ESP8266 FireBeetle board.

ESP32 / ESP8266 Arduino: Bitwise AND operator

In this guide, we will check how to use the bitwise AND operator on the Arduino core, running on the ESP32 and on the ESP8266. The tests on the ESP32 were performed using a DFRobot’s ESP-WROOM-32 device integrated in a ESP32 FireBeetle board. The tests on the ESP8266 were performed on a DFRobot’s ESP8266 FireBeetle board.
