AVT3040 B

What is it for? I think everyone knows what a room thermometer is for. The photographs show how the presented layout stands out. Mainly the way of displaying data - a rotating set of LEDs, controlled sequentially through an electronic system, creates an apparent (spectral) image, using the inertia of our eye. Many spectral display systems have appeared on EdW pages, but the thermometer has not yet been available. Of course, nothing stands in the way of reprogramming the microcontroller and using the device for advertising purposes. The thermometer was built based on the popular ATtiny2313 microcontroller.

Note: Everything should be done solidly and reliably, and then carefully balanced so that nothing is torn away during spinning !!!

The set includes a printed circuit board and programmed layout, a set of elements and documentation.
