    Arduino-esp32 course – Event driven WiFi and build_flags configuration – Chapter 2

    On this new release we will focus on connecting our Espressif board to WiFi and will also the powerful build_flags to inject the defines directly on compilation time. This will make our WiFi configuration easier and leave it in a place where it can be easily configured, again in our platformio.ini project configuration file: [env:espressif8266]…

  • Arduino-esp32 Basic course – Getting started – Chapter 1

    First of all, this small series of blog posts, assume you have installed and are familiar with Platformio IDE to edit and upload code to your Espressif chips. We ‘ve covered in another post the installation and getting started part with this nice IoT editor. Please refer to this section of Platformio to get the…

  • Trying out Waveshare E-Paper ESP32 driver board

    Trying out Waveshare E-Paper ESP32 driver board

    In my pursuit to make the CALE displays as small as possible but also to learn how different boards interact with Epaper I got last week an Waveshare E-Ink ESP32 driver board. Not all the boards need to use the default SPI GPIOs of the ESP32 and this was one of this cases. Opening the…

  • Cordova cross platform mobile applications

    After the small Chrome App experience that resulted in a very compact app that reads Video and sends an UDP binary stream to ESP32 Led controllers I decided to start learning how to program a real mobile app. Real because I find that the way to do it must end in the App Store and…

  • Met Remora a simple firmware and language to launch addressable led animations from ORCΛ

    Met Remora a simple firmware and language to launch addressable led animations from ORCΛ

    Remora listens to UDP short commands to trigger LED Animations. Receives ; commands from ORCΛ As a side fun idea while learning Nodejs and while working for a bigger and more complex project with my partner Hendrik I programmed Remora just to have an easy way to launch animations from ORCΛ If you want to…

  • Espressif ESP-Mesh updates their App with a new UX

    About a month ago I started learning to use ESP-IDF and got very interested in Espressif Mesh Lamps. It’s a lot of fun for me to create my own ESP-Mesh LEDs lamps with this technology. But as with everything I touch that is open-source, apart of being a user, I try to collaborate and made…

  • ESP-IDF Libraries in Arduino framework

    I started to dig a bit more into the Iot development network from Espressif with the intention to slowly learn something new. All the official examples of Mesh lights, ESP32-Camera and ESP-WHO that presents a preliminary version of face recognition are built on the top of the IDF. So sooner or later, I think will…

  • Starting to do smart-home appliances with ESP-Mesh

    “ESP–Mesh reduces the loading of smart light devices on the router by forming a mesh with the smart light device.” I’ve started months ago getting some smart lights for home and I’ve chosen Osram since it was about half the price than Phillips VUE. But the thing with this systems, though they work nice and…

  • Simple IoT image logging using BigIot.net

    Since beginning of 2019 I’m participating in a project called “Low cost / low power sleep / WiFi Camera” so I purchased a couple of low cost boards, between them the LilyGO ESP 32 Camera. BigIot.net is an interesting IOT API site Not only an API but a very interesting infrastructure that is also possible…

    PlatformIO: An alternative to Arduino IDE and a complete ecosystem for IoT

    As an introduction I would like to make clear that I’m not a C++ advanced coder or IoT professional, I do this just because it’s a challenge, and because it’s a lot of fun compared to my 9 hrs/5 days a week web developer doing PHP and Admin panels for clients in Germany. Two months…
