As always, there is a wealth of information online on how to configure the Arduino GUI. Therefore, I'll keep this section very brief, referring you to the sources linked below for more detailed information. IDE Configuration In the settings, enter the following URL: http://arduino.esp8266.com/stable/package_esp8266com_index.json Start the Board Manager: Search for ESP8266 and the sources …

With the help of this add-on board, the Arduino can communicate via Wi-Fi. The board has an ESP8266 microcontroller on board, which can handle the network communication. Upon delivery, the ESP should have firmware from AI Thinker installed. How to find this out and much more I have summarised so compactly in this post. On the web…

Sensorknoten sollen möglichst lange und unabhängig arbeiten können. Dennoch benötigen sie Strom, um mit der vorhandenen Energie möglichst effizient umgehen zu können, hat der ESP8266 und andere Controller die Möglichkeit in den Tiefschlaf zu gehen. Das schöne ist er kann sich nach fast beliebiger Zeit selbst wieder aufwecken. Ein Nachteil beim ESP8266 ist das er …

I came across the term MQTT online and really liked the approach behind it. So, I treated myself to a small experimental setup, which I've described below. First, a few details about MQTT. About MQTT General Information MQTT governs communication between data sources and data sinks using a broker. Data Source Sources for…

There is an expansion board with a motor driver for the NodeMCU V2. It allows two small motors (up to 1.2 Amperes) to be controlled via an L293DD motor driver. It is also possible to connect a stepper motor. Furthermore, it offers two separate connections for the power supply of the board and the motors. Most of the ESP pins are brought out with an additional ground/power pin, which makes connecting...

I still had two OLED displays from a test and was wondering what I could do with them. Since I've been experimenting with nodes with integrated displays lately, I was planning to give my old ESP8266 NodeMCU V3 a bit of a boost. I want to briefly outline the process here; don't hesitate to ask questions and leave a comment. ...

A development board with the ESP8266, including a USB interface for programming and serial communication. The board can be powered via the USB port, via 5 volts on the Vin pin, and with 3-3.6V on the 3.3V pins. All connection pins are led to the outside; the node just fits onto a breadboard. Views Front view Top...
