Motion sensors are key components for security systems and are very useful when paired with IoT. In this tutorial, we’ll use one along with an ESP32 which will send an MQTT message based on the sensor’s state. Another ESP32 with a connected LED will receive
Opening and closing a chicken coop door is a repetitive annoying task that must be performed at the right time every day. In this tutorial, we will show how a small ESP32 can be used to automate this chore away by building a toit servo
In this tutorial, we’ll have a look at how we can create an MQTT sensor for Home Assistant with ESP32 and the Toit platform. Home Assistant is one of the largest open-source platforms for home automation and is very popular for managing things through IoT.
An ESP32 board will read pres and temp from BMP280 sensor and log the readings to Google Sheets. Furthermore, we’ll also send email alerts.
In this article, we’ll have a look at Toit’s PubSub API and show how we can use it to control a small DC motor remotely using Toit. An N20 geared motor will be hooked up with an L9110s motor driver to control its speed as
If you’re building an extensive digital system-based project or even a product, then some form of digital communications between various subsystems has to be there. The communications may be using UART, I2C, SPI, I3C, etc., but sometimes things might not work out as expected after
Running computer vision applications based on machine learning used to be troublesome. It would generally require a lot of computational power to get a useful result. However, with the introduction of Tensorflow Lite for microcontrollers, the world of tiny machine learning (tinyML) devices is growing
We recently saw the Himax WE-I Plus EVB development board which boasts some really interesting hardware for performing AI on the edge. In essence, the board is powered by WE-I Plus ASIC (HX6537-A) and can classify a single image at 96×96 pixels in just over
Automation through Artificial Intelligence (AI), we feel, is the present and future of our society. The ongoing Fourth Industrial Revolution (Industry 4.0), which allows our industries to automate industrial processes, confirms this. To achieve such autonomy, smart computer vision and sensors play an important role.
With the recent boom in Artificial Intelligence technologies, there’s a huge demand for hardware capable of performing AI on the edge. So, a lot of electronics manufacturers are coming up with their own products, flooding the market with numerous AI boards. To stand out from
