Blynk is an IoT-platform that consists of a Blynk server, custom projects within an iOS/Android mobile app and custom hardware IoT-nodes (Arduinos etc) using a Blynk library. The mobile app communicates with the hardware via the Blynk server and you can use the mobile interface for displaying sensor data from the hardware nodes or control […]Read More Blynk, PlatformIO and ESP32
In two previous posts, I used the RCSwitch and pi-switch libraries for communication between an Arduino Uno and a Raspberry Pi. I touched briefly on the main purpose with these libraries – to control RC outlets. In this post I will dig deeper and decode the RC signals so that the remote control can be replaced […]Read More RCSwitch revisited – control RC outlets with a web app
Adafruit hosts a cloud service, io.adafruit.com, where you can upload data from your devices and also subscribe to data from other devices. The service is currently in beta, but you can sign up for a free account to test it. The data is stored in “feeds” and you can configure your own dashboards for viewing […]Read More Exploring Adafruit IO
ESP8266 is a very popular and inexpensive WiFi-chip that can be a real contributor for taking small gadgets to the Internet. I recently bought an Adafruit Feather Huzzah ($18). It is build around ESP8266 which means WiFi-connectivity, but has some additional features compared to the simpler ESP8266 modules available: A USB-port for serial transfer and programming […]Read More Meet the Huzzah!
Now that I have a Raspberry at my disposal, it is possible to install Windows 10 IoT on it and explore what Microsoft have made available for the Pi. Why would I run Windows 10 IoT on a Raspberry? I don’t know yet, but as Windows 10 IoT is free, let’s try it out! For […]Read More Getting started with Windows 10 IoT
Last week I finally got around and bought my first Raspberry Pi. Getting it up and running with Raspbian via Noobs was a breeze and after playing around with the OS and Python for a while I decided to get some real use out of this little machine. My first experiment aimed at a home security […]Read More Raspberry Pi & PS2 EyeToy
