# ON Delay This function block delays the activation of a boolean signal. When the input signal switches from False to True, the block waits for a configured amount of time before allowing the output to go True. If the input returns to False before the delay elapses, the output remains False. ## đŸ“Ĩ Inputs (sockets) * `Input` Provide a boolean signal to be delayed. ## 📤 Outputs (sockets) * `Output` Delayed boolean signal. Becomes True only after the configured delay following an input rising edge. ## 🕹ī¸ Controls (widgets) * `Delay Time` Text field where you enter the delay duration in seconds. Enter numeric seconds (for example 5 for a five second delay). ## ⚙ī¸ Running mechanism * The block monitors the provided `Input` signal. * On a rising edge (when `Input` changes from False to True), the block starts a timer for the number of seconds specified in `Delay Time`. * While the timer is running the `Output` remains False. * If the timer completes and the `Input` is still True, the `Output` becomes True. * If the `Input` returns to False before the timer completes, the timer is cancelled and the `Output` stays False. * Subsequent rising edges restart the delay process. ## ✨ Features * Simple configurable delay for rising signals without additional scripting. * Safe cancellation of the delay when the input falls back to False. * Works with any boolean-producing blocks or signals in the system. ## 📝 Usage instructions 1. Connect a boolean source to the `Input` socket (for example a manual `Logic Input` or an event-producing block). 2. Set `Delay Time` to the number of seconds you want to wait after an input becomes True. 3. Use the `Output` as the delayed control signal for downstream blocks (for example to drive a `Led Output` or start a process). ## 💡 Tips and Tricks * Pair with `OFF Delay` when you need controlled delay behavior for both rising and falling edges (ON Delay for rise, OFF Delay for fall). * Use `Rising Edge` if you need to convert a sustained True input into a single delayed pulse or to detect the exact moment a transition occurs before starting other logic. * For manual testing connect a `Logic Input` block to the `Input` socket so you can toggle and observe behavior interactively. * Connect the `Output` to `Led Output` to visualize the delayed signal during tuning. * Combine with `Counter` to increment only after the delayed output becomes True, avoiding counts from short glitches. * Use logical blocks such as `And` or `Or` to gate the delayed output with other conditions before driving final actuators or logging. ## 🛠ī¸ Troubleshooting * If the output never becomes True after a rising input, verify `Delay Time` contains a valid numeric value and that the input remains True for at least that duration. * If the output becomes True too early, increase `Delay Time` to match the desired hold period. * If brief input spikes should be ignored, consider combining a short `Delay Step` or a pre-filtering logic so only sustained rises start the delay. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
