In this opportunity we will address a problem that has happened to us when we need to obtain the IP address of an Ethernet device, it can be a PC, Smartphone, PLC in our case it can be an Arduino with shield ethernet, ESP8266 or ESP32. If we do not have the possibility to see or know…

Review Solar Panel 10W with Arduino and Node-RED

For a long time I had planned to make some application with photovoltaic panel or common solar panel, in this opportunity I have acquired a monocrystalline solar panel of 10w perfect to power the devices we use in our tutorials. Although this is in design, we will perform a meterological station – Gateway later, and…

Test Module SD / MicroSD via SPI For Arduino & ESP8266

In this opportunity to test an SD Module and MicroSD with Arduino and ESP8266, in advance thanks to ICStation.com. We will not do a detailed tutorial on introduction to SD since there is already great documentation regarding the subject in intenet, but indicate the applications available for these modules. I introduce the SD module and Micro…
