Welcome to the New World of ESP
Introduction In this esp32 tutorial, we will check how we can get humidity measurements from a DHT22 sensor, with the Arduino core running on the ESP32. The DHT22 is a temperature and humidity sensor and you can check on the previous tutorial how Read More
Introduction In this tutorial we will check how to get the minimum sampling period of the DHT22 and how to use it to make some temperature measurements without crossing the maximum sampling rate the sensor suports. We are going to Read More
Introduction In this tutorial, we will check how to decipher data with AES-128 in ECB mode, on the Arduino core running on the ESP32. In this previous tutorial we have already checked how to cipher data with this algorithm, so Read More
I had created a very large project that was starting to consume too much RAM and needed to see where it was all going, and how to better optimise the use of the RAM…. I quickley learned no map file Read More
The objective of this esp32 tutorial is to explain how to create a very simple class and instantiate an object of it in the Arduino core. This code was tested on both the ESP32 and the ESP8266. The ESP32 tests Read More
The objective of this ESP32 / ESP8266 MicroPython Tutorial is to explain how to create a file in MicroPython. The code was tested on both the ESP32 and the ESP8266. Introduction The objective of this ESP32 / ESP8266 MicroPython Tutorial Read More
Introduction In this tutorial, we will check how to get the IP of a socket client that connects to a socket server hosted on the ESP32, using the Arduino core. You can check a detailed tutorial on how to set Read More
Introduction In this ESP32 tutorial we will check how to send data with a socket client on the Arduino core. Since we will need to reach a socket server, we will implement our own using Python. You can check in Read More
Introduction In this tutorial we will check how to generate the hash of a string using the SHA-256 algorithm on the Arduino core running on the ESP32, with the mbed TLS libraries. SHA-256 is a hashing algorithm of the SHA-2 Read More
Introduction In this ESP32 tutorial we will check how to develop a HTTP web server that will expose an API for clients to retrieve measurements of temperature, humidity and CO2. These measurements will be gathered from the surrounding environment using two distinct sensors. Regarding Read More
