Projects made with ESP32 board
Introduction Bluetooth is a communication system between devices that is now very widespread. We find it in our cell phones, computers, headphones and all those devices that need to communicate data over short distances and without wires. One of our favorite devices, the NodeMCU ESP32, has this type of communication natively (in addition to the […]
Introduction In this article we will see how to build a REST API server using an ESP32 NodeMCU. We have already seen an example of what REST APIs are and how to use them in the How to make a datalogger with the ESP32 NodeMCU connected to a Django cloud on Raspberry article. Basically, REST
Introduction In this article we will see how to use a Raspberry and REST APIs to receive and display, via a Django application, data detected by an ESP32 NodeMCU. We have already seen in previous articles (Thermo-hygrometer with clock and LCD display on Arduino UNO, How to make a data logger with the ESP8266 NodeMCU

Introduction We have already seen how to make a simple video surveillance system with the Freenove ESP32-WROVER CAM Board with camera in the article How to create a simple video surveillance system with ESP32 on PlatformIO. In that project the board sends us the images, through an embedded web server, to a certain URL that
Introduction Nowadays we all have to deal with video surveillance systems: on the streets, in shops, at home (to control unwanted access by any bad guys or perhaps to secretly observe the behavior of our pets in our absence). Today’s technology helps us as it provides us with increasingly miniaturized and cheap boards, cameras and
