In this tutorial we will check how read content from the serial port, using the micro:bit board. We will use the micro:bit pins as serial Tx and Rx pins, like we have already covered in this previous tutorial.
In this tutorial we will check how to receive binary frames from a websocket client in a server hosted by the ESP32. The tests were performed using a DFRobot’s ESP32 module integrated in a ESP32 development board.
In this tutorial we will check how to send data in binary frames from a Python websocket client.
In this short tutorial we will check how we can pause the execution of a program on the Micro:bit, running MicroPython.
In this tutorial we will learn how to turn on and off specific LEDs from the micro:bit‘s LED matrix, using MicroPython, including controlling their brightness.

In this tutorial we will check how to use the * operator to generate a repetitive sequence of a string. This tutorial was tested on MicroPython running on a micro:bit board.
In this tutorial we will check how to receive textual data from a client on a websocket, using the ESP32 and the Arduino core. The tests from this tutorial were performed using a DFRobot’s ESP32 module integrated in a ESP32 development board.
