For some weeks I have done some tests with a LOGO! (logical module) from Siemens, for a few months I have seen that they use it in basic industrial applications, although I do not personally consider it 100% a PLC, it is easily integrated into monitoring and control applications for simple processes. You could say…

Update HTTPS Redirect Version 2.0 ESP8266 & Google Spreadsheets
In previous tests we made the communication of an ESP8266 module and bidirectional sending of data to a Google Sheet with the help of Google Script, Initially thanks to Sujay Phadke “electronicsguy” the creator of the HTTPSRedirect library, a few months ago I made considerable improvements to said library and we will do a quick…
Communication LoRa ESP8266 & Radio RFM95 #1
One of the most named technologies to be implemented for the Internet of Things, which has very striking features long distance communication and low power reflected in its low consumption, LoRa “Lo ng – Ra nge”, this type of modulation has been become very popular in data sending and receiving projects, there are some libraries…
Controlling Arduino from Node-RED with Firmware Firmata
In this opportunity we will use Node-RED to control an Arduino MEGA 2560 R3, thanks to the collaboration of a colleague Absolutely Automation I indicated this method that allows to easily control an Arduino if complications. Also in one of the comments does anyone consult if there is a more practical way to control from…
Introduction library WifiManager
The main disadvantage is to configure the network credentials in a esp8266 without requiring to modify and download the firmware again, I have tested with several methods to dynamically store the SSID and PASSWORD of a network. In the case of the esp8266 programmed in Arduino IDE for some time I have seen a proposal…
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…
Introduction Plataform InitalState & ESP8266
This time we tested the Initialstate platform, is an IoT platform dedicated to the collection and visualization of data, creating colorful graphics. For our test we will use the ESP8266 Module and a DS18B20 Onewire sensor to collect temperature and then visualize it. Safely send time series data to your account from sensors, devices, software…
