Projects made with the NodeMCU
Introduction If you’re looking to control an SG90 servo motor via Bluetooth, the ESP32 is an ideal solution. The ESP32 is a very powerful microcontroller that offers built-in Bluetooth capabilities, making it perfect for remote control projects. In this article, I’ll walk you step-by-step through the process of setting up the ESP32 to control an […]

Introduction In this article, we’re going to build a fairly simple project: a system that controls the brightness of an LED based on the ambient brightness. In practice, the lower the ambient brightness, the more the LED lights up and vice versa. For the detection of ambient light we will use the well-known BH1750 sensor

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 Arduino Cloud is a web platform that serves to connect with devices such as Arduino, NodeMCU and so on in order to collect the data sent by them and display it on a dashboard. It also allows you to control these devices by specific commands on the dashboard. It also has the possibility of

What is the the EEPROM memory The EEPROM memory (acronym for Electrically Erasable Programmable Read-Only Memory) is a type of memory present in many electronic devices (including our beloved devices such as Arduino or NodeMCU ESP8266 / ESP32 etc) used to store small amounts of data in a ” almost” permanent way. In practice, the

Creating the project using PlatformIO Today we want to see how to create a new project for the NodeMCU ESP8266 board using the PlatformIO IDE and how to add external libraries to the project. Please note that the operating system I use is a Linux distribution (specifically Fedora 36). So the folder structure in the
