The monitor itself is a fairly straightforward Arduino build using a couple of DS18B20 1-wire temperature sensors and a real-time-clock module and displaying their readings on a small OLED screen.

We have featured quite a few cool clocks here at Geeky Gadgets, and the latest one is the work of Andrew O’Malley, the DOTKLOK, which is an open-source Arduino digital clock. The DOTKLOK comes ...

An Arduino sketch reads voltage and current data on the analog ports and displays measurements on the display. The measured data is averaged to filter out noise. The OLED display has a SPI ...

Those of you that enjoy using the Arduino platform to build electronic projects, a new WifiDuino device which has this week launched over on the Indiegogo crowd funding website, ma be worth more ...

Call it synchronicity, or manually setting a 16-bit number in an Arduino, or how to turn an OLED into a rotary dial... What am I talking about? Well, I was just compiling the blogs pages for the next ...
