The tiny Pixel 2.0 is basically an Arduino board wedded to a tiny 1.5″ 128×128 color OLED screen. This means you can stick it inside a wearable and address the screen directly from the Arduino ...

Touch on the display is five-point + gesture, and the camera interface is 20pin ‘Arducam’. Power comes from the underlying Arduino, and when the display is attached there is still access to all 54 ...

It powers the Arduino mini pro which drives the 1.8″ LCD screen and actuates the optoisolator which is responsible for triggering the camera. On the right you can see the clear knob of the ...

so whipped up a neat design using analog meters to display the time. The build relies on that old stalwart, the Arduino Uno, to run the show. It’s hooked up to a DS3231 real-time clock module so ...
