And `DONE` pin, which pulses when reading is done, wherever the button is pressed or not.\n\nThis is a standard idiom for side-effect nodes representing hardware or, for example, the Internet.\n\n## Exercise\n\nLet's make the LED glow while the button is pressed.\n\n1. Assemble the [circuit with a button and LED](https://xod.io/docs/tutorial/104-button/?utm_source=ide&utm_medium=ide_comment&utm_campaign=tutorial#circuit).\n2. Set the `PORT` value of the `button` node.\n3. Link `PRS` to `LUM`.\n4. Upload your patch.\n\nHold the button to turn the LED on.",
