Russell Eveleigh is using a Raspberry Pi Pico to demonstrate Dijkstra's algorithm visually with LEDs arranged as a map of the Cotswolds in England.

In algorithms, as in life, negativity can be a drag. Consider the problem of finding the shortest path between two points on a graph — a network of nodes connected by links, or edges. Often, these ...

Using our favorite microcontroller, the Raspberry Pi Pico, he's put together a beautiful LED focused project that demonstrates the Dijkstra's algorithm in action.
