In this example we have tried to send and receive data from a database in real-time in Firebase, learning how to create the DDBB, the application in Arduino, and then finally to access it from a mobile application created with App Inventor. Let’s see each part in detail.
Here we present our first tests with the Pixy camera, a device capable of detecting the colour of the objects, and to track their position. Until a short time ago, it was really difficult to develop applications able to take advantage of artificial vision algorithms, and most of all by using systems with limited hardware…
Prusa3D (a company that currently ships 1000 printers every month) announced a big firmware update for the Prusa I3 MK2 model that focuses on the current day kit builders out there I couldn’t have been happier. Already equipped with automatic mesh bed levelling, a large 25x21x20cm build volume, onboard LCD panel, heated bed, and just about every feature…
The Connected Health project aims to bring vital sign monitoring to the masses with a simple, inexpensive unit built around commodity hardware. This monitoring system is connected to the Internet, which enables remote patient monitoring. They developed the HealthyPi HAT for the Raspberry Pi as a way of opening up the healthcare and open source…
https://youtu.be/lK4v-6xzSEA This post will tell you everything you need to know about MQTT communication which will enable you to use it communicate between devices. We add an LED to the Arduino Nano 33 IoT board and this LED is controlled remotely from a switch that is connected to a WeMos D1 mini board. All communication…
Few days ago, Open Hardware Summit 2014 released an almost complete list of Speakers. The full list is available here: http://2014.oshwa.org/speakers/ The review panel has passed along the accepted speakers and I am thrilled at their selection. We have a great range of interest which will be represented at this years open hardware summit! Jump over…
In this project we see how to build an IOT-based dust monitoring system that can measure surrounding dust, send data over the Internet, and monitor the long-term value graphically. We use a Sharp gp2y1014au0f particle sensor which uses an IR LED and when the particle enters the sensor, the light bounces back to a photodetector….
