Hey, ever considered turning a brick wall into a live code mural, like a constantly updating display that reacts to traffic or footfall?

That’s the vibe I’m going for—just a wall that pulses with the city’s pulse. Let’s start with a basic API to pull foot‑traffic data, then wire an LED controller to map counts to color shifts. We’ll keep the code modular so you can tweak thresholds or add fancy transitions later. Ready to dive in?

Start with a simple loop: read the count from the API every 500ms, convert that number to a hue value, and write that hue to the LED strip. In code it’s basically ``` while true count = api.get('foottraffic') hue = map(count, 0, max, 0, 360) leds.set_hue(hue) sleep(0.5) end ``` That’s the first line—your wall will bleed color as people move. Once you’re happy with the hue mapping, add a fade to keep the motion smooth. Let me know if you hit a snag.
