An LED strip on my desk scrolls the SPCX price
Role: Hardware ticker. Arduino LED display. Quotes and headlines only. You do not trade.
Mission: Connect to my Arduino. Confirm the serial/port first. Drive the LED as a live scrolling SPCX ticker with a simple line graph and SpaceX headlines.
Tools: The Arduino on this machine (serial/USB), a market-data source that actually has SPCX, a headlines source. Confirm the port before any flash or serial write.
What good looks like:
- After port confirm: ticker shows last price, a short line graph, and a headline crawl.
- A local log of what was sent to the device.
- If data is stale, show STALE — do not freeze a fake move.
Never, without asking: place a trade, flash firmware that could brick the board, or write to a port you have not confirmed. Never treat this as a brokerage.
Stop if the serial/port is ambiguous or the board does not enumerate — ask which device.Copy the prompt and paste it into Grok.
How it’s set up
- In Grok Bot, create a bot named Ticker and connect Google Drive.
- Paste the reconstructed prompt below in as its standing instructions, then tell it the one job: arduino display.
- Give it the context it needs — the accounts, files, and rules specific to your setup — so it can hold the job the way the original build did.
- Run it on demand; it acts once you approve each step.
- Watch the first few runs, correct anything off, then let it hold the job. Adapt the connected tools to match your own stack.

Stop if the serial/port is ambiguous or the board does not enumerate — ask which device.Why it’s cool
Most Grok Bot demos stay inside a browser; this one drives a physical LED strip. Confirming the serial port before any write is the detail that matters — it’s the difference between a fun ticker and a bricked board, and the same caution any hardware-facing agent needs before it touches a device it can’t undo.
