3 min | 115454Quoting the official MicroPython's website:
MicroPython is a lean and efficient implementation of the Python 3 programming language that includes a small subset of the Python standard library and is optimised to run on microcontrollers and in constrained environments.
Besides C++ and C, I use MicroPython to program microcontrollers, especially the ESP32/ESP8266 types. These two microcontrollers are compatible with MicroPython and it is easy to integrate sensors and actors programming using this language. I wrote a tutorial about installing MicroPython on the ESPs, as well a lot of articles a...

1 min | 1136LeMaRiva|tech wishes you a Merry Christmas and a Happy New Year! To celebrate I made a video using the Xmas-lights from last year, but this time I connected the ESP32 to a Jupyter kernel to control the lights. A new Jupyter-ESP32 tutorial is coming soon. In the meantime, you can track Santa and spend time with your family!

2 min | 4700#Zerynth: ESP32 & Google IoT Core - Part 2: Getting data from Smart Power Outlets
Cloud Platforms, Home Automation, MicroPython | 2 min | 4700
This part 2 of the tutorial will allow you to get data from the smart power outlets and send it to the Google Cloud Platform (GCP) throught the Google IoT Core and using an ESP32 programmed with Zerynth (Python). This data is not usually available to the user (directly, you need to use the power outlet application), and it is sent to the company servers.
If you want to check, if your power outlets are compatible for this tutorial, they should have the...

Home Automation, MicroPython | 5 min | 24370
Today there is a wide range of offer for home automation devices. A lot of sensors, actors etc. can be connected to the cloud and be controlled using Google Home, Amazon Alexa, your smartphone, etc. There are a lot of companies offering low cost devices, e.g. Sonoff, Tuya, Teckin etc. Most of these solutions are based on ESP32 or ESP8266, and all of them send data to cloud solutions usually deployed on Amazon services, and the data is only accessible using the Androi...

3 min | 44280LoRa (Long Range) is a patented digital wireless data communication technology. It was developed by Cycleo of Grenoble in France and then acquired by Semtech in 2012. Semtech defines the Lora Technology "as the DNA of IoT, which connects sensors to the Cloud and enables real-time communication of data and analytics that can be utilized to enhance efficiency and productivity".
To sum up, LoRa is a wireless data communication technology that enables very-long-range transmissions (mo...

4 min | 32334One of the most visited articles on my blog is the Getting started with MicroPython! tutorial. If you still don't know what is MicroPython and you want to start programming microcontroller boards (ESP32, ESP8266 etc.) using a small version of Python 3, you should look at that article . Don't expect to use machine learning or/and other big libraries (the available RAM and microcontroller performance is far away for that aim), but you can do some projects like these:

1 min | 10525While I was reading my getting stated tutorial about MicroPython again, I noticed that I've forgotten to tell something about dependencies or packages.
Here is possible to find some MicroPython packages. On the WeMos (ESP32) or the ESP8266, it is possible to install these packages using the
upip
package manager. The WiPy doesn't have the package.To download the new packages, you need to connect the board to the Internet. I take the WeMos as example and typing the following, you can connect the board to your WiFi router:
ssid_ = <your_ssid> wp2_pass = <your wpa2 password> import network sta_...

4 min | 2328It has been a while since my last post! Sorry, I was a little bit busy and then I was on a business trip in Melbourne for the CDC2017 and then I had a week holiday in Bangkok. I will be posting some photos on the next days!
It's been a year now since I started this blog. It's a hard job to maintain it up-to-date but I still have fun writing and coding for this purpose! So let us start!
Intro
The first video that I published a year ago was using the Wipy2.0 and a WS2812b led strip...

Nov - 2017Hacking, MicroPython
5 min | 13654At the beginning of October I wrote a blog article called White Hacking: WeMos and SquirelCrawl!. I used the WeMos (ESP32) and the firmware provided by Hacker Arsenal to do a captive portal. As you known, a captive portal is a web page which is displayed to newly connected users before they are granted broader access to network resources [wiki]. This can be used in combination with evil portals to obtain login credentials. The firmware provided by Hacker Arsenal has mul...

5 min | 4452I was surfing the services that Google offers, I found the Geolocation API. As Google describes the API: it returns a location and accuracy radius based on information about cell towers and WiFi nodes that the mobile client can detect. As I was writing the last post using MicroPython, I thought the WiPy 2.0/3.0 could be a nice "mobile client".
To use the API you need to get an API key from Google. As a standard user of the API, you get:
- 2,500 free requests per day, and
- 50 r...
