#Deal: digital barometer BMP085 / BMP180 for Arduino, ESP8266, ESP Easy, Raspberry Pi projects

The digital barometer BMP085 / BMP180 allows measurements of atmospheric pressure from 300 to 1100hPa in your Arduino projects ESP8266 (ESP Easy), Raspberry Pi ... The selected modules use the I2C protocol to transmit the measurements to the Arduino ...

#Deals: ESP Easy compatible sensors, actuators, analog or digital inputs

The ESP Easy firmware supports a very large number of sensors, actuators. If you are limited by the unique analog input and the number of inputs / outputs offered by ESP8266 WiFi modules, you can add analog or digital input boards. Atmospheric ...

IoT development based on Orange Pi, Arduino (Firmata), Nodejs, Blynk and Johnny-Five

In this tutorial, I propose to combine Nodejs/Johnny-Five with Blynk to remotely control the GPIO of the Arduino/Firmata from a smartphone or a tablet and to make measurements (temperature and atmospheric pressure of a BMP180 in ...

Start programming with Node Js and Johnny-Five: IoT and robotics based on Arduino, Raspberry Pi, Orange Pi

Johnny-Five is an open source Javascript library that allows the rapid and easy development of connected objects or small robotic projects (articulated arm, radio-controlled car ...). In the previous tutorial, we saw how to ...

ESP8266 (Web Client): Sending Data to Jeedom in TCP / IP Wireless (JSON API) – Part 1

We continue our series of articles on HTTP (TCP/IP) data exchange between an ESP8266 and the Jeedom Home Automation Server. Jeedom provides an API as complete as Domoticz. The documentation is available here. We will go a little faster than for ...

Driving the GPIO of the ESP8266 (Web Server) from Domoticz to TCP/IP Wireless – Part 2

We continue today the tutorial dedicated to the exchange of data between Domoticz and an ESP8266 by HTTP request and more particularly how to control the GPIO from Domoticz. In the previous article, we set up sending data from an ...

ESP Easy: firmware ESP8266 to create connected and home automation objects without programming

ESP Easy is an open source firmware that allows to program ESP8266 modules without any line of code (official page of the project). ESP Easy has evolved a lot since the 78 version I used in the previous article that explained how ...

ESP8266 (Web Client): Sending Data to Domoticz in TCP/IP Wireless (API/JSON) – Part 1

In this tutorial, we will use the ESP8266Client and ESP8266HTTPClient libraries to implement TCP/IP communication between and an ESP8266 NodeMCU module and the Domoticz API/JSON interface. We will use a temperature and humidity ...

ESP8266 (Web Server – Part 5): how to use Google Charts to display gauges and charts

Now that we have a records we will add graphics to the Web interface of the ESP8266 using the Google Charts library. There are many libraries to create graphics and gauges in Javascript / HTML5. Google Charts is a very rich ...

ESP8266 (Web Server – Part 2): Interaction between Arduino code and HTML interface

Here is the second part of the tutorials devoted to the creation of an HTML interface stored in the SPIFFS zone of an ESP8266 functioning like a web server. In this tutorial, we will add the code needed to implement the ...
