Recently Adafruit introduced the STM32F405 Feather Express. Mounting an STMicroelectronics STM32F405 32-bit Arm Cortex-M4 processor running at 168MHz, 1MB of flash memory, a 2MB SPI flash module. It also features an onboard NeoPixel indicator and a Qwiiic/STEMMA-QT compatible connector for solderless hardware interfacing over I2C. The board is fully compatible with Python and only…
We make a NeoPixel light installations using Fishino and NodeMCU, controlled via Wi-Fi from PC or Raspberry Pi through a Python library. A few years ago, the American Adafruit Industries revolutionized the LED market by introducing its NeoPixels, whose main feature is to integrate, in a single package, an RGB LED and its controller….
This article is a getting started guide for the ESP32 development board. If you’re familiar with the ESP8266, the ESP32 is its sucessor. The ESP32 is loaded with lots of new features. The most relevant: it combines WiFi and Bluetooth wireless capabilities and it’s dual core. From OpenStore More info
Let’s make a Dashboard for the gateway Antennino network, using open-source software that allows us to implement a control panel for our wireless devices. We left, at the end of the first episode after describing the hardware of the new Gateway for Antenninos, based on the powerful NodeMCU ESP 32, and introducing the…
https://www.youtube.com/watch?v=aKC7o6cbQiA I’ve been working on a little ESP32 expansion board/shield for an LED project I’ve been working on. One of the nice things about the ESP32 is that it has a peripheral known as “LED control” that provides 16 independent channels of PWM for controlling LED brightness, and my project uses that capability. One…
A new application of the Antennino board that realizes a gateway using open-source software, which allows us to realize a control panel (Dashboard) for our wireless devices. We have introduced you, in issue no. 225, to our Arduino IoT version with a wireless connection, not surprisingly named Antennino; this board can operate, depending…
Let’s switch on the house lights using voice commands given through Google Assistant and the ESP demoboard for WiFi connection. Google is one of the most innovative companies in the IT sector and it’s testified by the exorbitant number of users who use its services: from the most widely used search engine to the…
Espressif, a public multinational fabless semiconductor company, has partnered with Temboo, an enterprise IoT software leader, to offer support for ESP32 on the Kosmos IoT System. The integration of Espressif’s popular ESP32 line with Temboo’s award-winning Kosmos IoT Platform will allow users to research, design, and build the next generation of connected products with…
A multifunction platform built around BBC’s micro:bit educational board. It integrates a cute robot, a starter kit and also a board for experimenting. Some time ago, in a previous article, we have reviewed the micro:bit controller designed by the BBC as an object aimed to develop logic skills and competencies in the field of computer…
A new open source Espressif ESP32-based board offering a form factor similar to popular single board computers such as the Raspberry Pi Model A / 3 Model A+ has been launched via the Crowd Supply website this month and takes the form of the Obsidian ESP32. Obsidian ESP32 is an Espressif ESP32-based board adopting the familiar form…
SparkFun has released the company’s first open-source, embedded-systems module—SparkFun Artemis, Engineering Version—to empower engineers, prototypers, and R&D teams to integrate the TensorFlow machine-learning platform into any design. Additionally, the team has launched three boards with the unshielded module: BlackBoard Artemis, BlackBoard Artemis Nano, and BlackBoard Artemis ATP. Built around the ultra-low-powered Ambiq Micro Apollo 3 processor, and powered by…
If you’re dealing with brushless motors, you can be interested in this brushless speed controller by Electronoobs. Version 1.0 of his open-source ESC design has been just released. This is a sensorless brushless motor speed controller since it uses no sensor to detect the rotor position. Electronic speed controllers are used to control brushless motors;…
