TouchDesigner is a powerful visual programming environment for building interactive multimedia systems. Integrating various sensors allow interesting user experiences to be created. There are a number of ways to interface with TouchDesigner …
Instead of an online dashboard or physical indicator, here we look at a very different but interesting way of communicating the moisture level to the user: by sound! Here we …
Most of the time when you think of Internet of Things, you’re probably thinking of sensors and actuators that provide or affect some kind of environmental phenomena such as temperature, lighting, …
Having made a nice automated plant monitoring and watering system, in this post we describe the process of adding physical gauge to it using a small servomotor. In this case …
Introduction In a previous post we described the overview and hardware setup of an automated plant watering system. Here we take an in-depth look at the node-red flow, including the configuration for …
Using the Raspberry Pi plugged into an external monitor, PiShield and one or two simple sensors, we can build an automatic page tuner for playing music. Before delving into the …
As you may know, the Raspberry Pi comes with a free version of Wolfram Alpha. Wouldn’t it be great if you could work with sensor data within the Wolfram environment? Well, …
Similar to the MIDI input example, we can output MIDI in node-red as well. The following shows the midi out node, with MIDI data injected for note on and off …
In this node-red project, we make a simple “people counter” as you might find at store entrances, as well as an optional addition to take pictures or videos using a …
Do you have trouble keeping your plants alive? Have you ever wanted to build an automatic plant irrigation system? Want to build something cool with your Raspberry Pi? With some …
