The POV yellow lace is an idea that came out initially as a protest. Continue Reading →
I’ve designed this dimmable Arduino RGB led driver board to be cheap and easy to build. This board has 3 separate driver channels for R, G and B leds with up to 1A each. The final user can regulate the output current by setting reference voltage resistors.
If you are looking for a led driver that is simple and cheap to build here you can find instructions on how to build your own.
In this part we get our hands dirty by installing the sensor and putting the code in the arduino energy meter. Our “Hello world’ of energy metering.

For those interested, Arduino MKR1000 is a new board that Arduino is launching the next February 2016. It’s focus it in the IoT realm. Arduino and Microsoft have joined forces and initiate a contest which the 1000 first pre-selected candidates will win a brand new Arduino MKR1000 board before they are even released to the public.

Usually I do constant research on projects to automatize things at home, like energy monitor. Long time ago I came across this little nice post, explaining in a very simple way how to monitor your home energy consumption. On top of that he is using an ethernet shield that outputs the information through a MQTT feed to xively.com where it is processed and transformed in a nice bar graph.
UPDATE: Xively is not free anymore so this example will not work. Soon I will post an alternative using other types of logging.
UPDATE2: Here you can check another project using sparkfun server and thingspeak server
