  • Temboo, Twilio and Nexmo: SMS and voice messages from your IoT device

    In this post, I will provide an overview of how to use Twilio and Nexmo to send SMSs and voice messages directly from your device. I will use a Particle Photon but this also works from an Arduino, or a Raspberry Pi or basically any other system. The reason for this is that I will Read more

  • Controlling Sonos from a Particle Photon

    Now for something fun! Let’s control a Sonos from a Particle Photon and a connected button. I connected a Grove Button to the Particle with simple male-to-female wires. The SIG line on the button should go to a digital port (D0 in my case). When the button is pressed, the port will read HIGH and Read more

  • Particle and Azure IoT Hub: forward events for storage and analysis

    In a previous post about Partice published events, you have seen how to publish custom events to the Particle Cloud. Other devices or applications can subscribe to these events and act upon them. What if you want to do more and connect these events to custom applications? In that case, Particle has a couple of Read more

  • IoT with Particle and Porter

    In an earlier article, we took a look at Particle Functions and Variables. We wrote a simple application that can blink an LED with a function and read the value of a photoresistor with a variable. Although you can easily call the function or read the variable with the Particle CLI or with a REST Read more

  • IoT with Particle: publishing events

    In the two previous posts, we discussed setup and talked about triggering actions and reading sensor data. Particle also allows you to publish events. You can subscribe to these events or pass them to other systems such as Azure IoT Hub. Let’s build on the previous example with the LED and the photoresistor. When we Read more

  • IoT with Particle: Functions and Variables using the Build IDE

    In yesterday’s post, I talked a bit about the setup process and initial configuration of a Particle Photon. To start quickly, we used the Tinker firmware and the Particle iOS app to light up a LED using digitalWrite to light it up with full brightness (full 3.3V) but also with analogWrite to vary the brightness Read more
