Arduino Star Chart: Building a Micro Planetarium with an Arduino and TFT Screen

This 3-minute video describes the hardware and provides a demonstration of an Arduino being used to generate star charts. The software is standalone, it doesn't require a WiFi connection. It requires an Arduino with at least 128 kbytes of internal Flash storage, and at least 32 kbytes of internal RAM. It also needs an external Flash memory chip to store the star catalog. For more detail including source code and circuit diagram, please see this article: https://community.element14.com/chall... If you build it and have technical queries about it, please comment in the comments section at that link, because you'll be able to supply code snippets and screenshots there, to make things easier. It's a bit difficult to troubleshoot via YouTube comments : (
