" summary

Hands-on demo uses Remix and MetaMask for deploying consumer contracts and the Hardhat starter kit to send Chainlink Functions requests. Shows Price Feeds wired by address, creating a subscription, funding it with test LINK from a faucet, adding a consumer, and calling getLatestPrice and requestRandomWords. Uses a DON of ~16–32 nodes, heartbeat/threshold update logic, and automation with checkUpkeep/performUpkeep; VRF returns verifiable random words and automation increments a counter, proving end-to-end functionality.
