Cheerlights is an awesome example of an IOT (Internet Of Things) collaborative project. It allows all users lights across the world to synchronize to one color. For that, it uses a Thingspeak channel and API. More information about the project you can visit its page.
For an event here in my home town (Eletrónica e Informática, pela AICB), I decided that I wanna do some Bluetooth project and while browsing through a Chinese store, I stumble into a wood phone booth – and it just hit my mind – another RGB lamp, controlled with Bluetooth and an Android app. I did the wiring and the programming, my lovely wife has taken care of the aesthetics .
- 1x Arduino Micro (any other could do – but beware of the pwm pins)
- 1x Bluetooth 4.0 LE HM-10
- 1x Adafruit Neopixel Ring 16 x 5050 (or anyone compatible with WS2812 5050)
- 1x Power Supply 5V, 2A for Arduino Micro (the end mus be micro usb)
Xibo is a powerful Digital Signage content management system and suite of signage players.
Digital Signage, from Wikipedia, is a form of electronic display that shows information, advertising and other messages. Digital signs (such as LCD, LED, plasma displays, or projected images) can be found in public and private environments, such as retail stores and corporate buildings
A few months ago i bought a 3.2” TFT display from banggood for my Raspberry PI. After a few days trying to put it to work, here’s how. My approach doesn’t uses any custom kernel
First, a few specs for the TFT
Display module: flexfb, fbtft
Touchscreen module: ads7846 (more…)
I bought a new MinimOSD MAVLink OSD from Bangood to use with my CC3D Flight Controller and had trouble to connect it to the computer. After a while, I managed to have success. Here’s how

In another post, I’ve shown how to communicate with Arduino through Bluetooth. Arduino is a very nice platform for electronics, but sometimes, we need a full computer for more expensive workload.
Here, I’ll show how to share information between the Arduino and the Raspberry PI. Imagine that you have the Arduino taking measurements and send them to the Raspberry PI to work on the data – a web server for example.

For a project I’m working on, I was searching for a method of sharing information between the Arduino and a Raspberry PI and Bluetooth came to mind. So, I start exploring.
Here’s a small example of a Wireless connection between Arduino and an Android Phone using Bluetooth.
