Share & Learn – Programming Design Automation & Control
There are a lot of tutorials DC voltage measurement with Arduino, in this case I found a tutorial that I consider the best functional method to measure DC without requiring input values of resistance, only requires some resistance and a multimeter, In next tutorials we will start with solar panels and we need to measure…
For a long time I wanted to test Mongoose OS, this time we will make a brief introduction and installation in a Linux operating system “lubuntu” Ubuntu/Debian. Mongoose OS is an open source operating system for Internet of Things (IoT) and low power microcontrollers such as ESP32 , ESP8266 , TI CC3200, STM32 license Available under dual GPLv2 / business…
This time we will install and configure Espressif IoT Development Framework platform (ESP-IDF) from scratch, this is the official espressif development platform for the ESP32 modules. In previous tutorials we talked a little about the ESP32 that have Wi-Fi (2.4 GHz band) and Bluetooth 4.2 in a single module among other features. ESP32 eBox&Widora first review I took…
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…
For a long time we have made our tests in protoboard, I think we already have a lot of tests that deserve a prototype for more robust applications, decided to take up the electronic design and I have found JLCPCB to provide a PCB manufacturing service at a price that very reasonable. Based on some…
More than a year ago Espressif released the long-awaited ESP32, these modules are low cost microcontrollers, low power consumption, Wi-Fi chip, Bluetooth and what is really amazing the Tensilica Xtensa LX6 dual-core microprocessor !!, another interesting fact has improvements in security and secure connections, is the successor of esp8266. Unlike ESP8266 espressif design the ESP32…
The following implementation using an ESP8266 module and a temperature sensor ds18b20 allows the configuration and sending of data to Emoncms without requiring to modify or edit a line of code, facilitating the creation of parameterizable applications. After testing the Wifimanager libraries, which allow an agile configuration of the network credentials and additionally allow to…
We have done a lot of testing on this platform Emoncms part of the OpenEnergyMonitor Project, which has very attractive features if you decide to monitor or control your “bugs” Arduino, RPI, Esp8266 … Although we will emphasize on the platform, it is important to know the main mission of the OpenEnergyMonitor Project. is a tool…
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…
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…
