# Logic Input This function block provides a simple manual boolean control you can use to trigger or gate other blocks in your scenario. Use it when you need a human-controlled TRUE/FALSE signal inside the flow. ## 📥 Inputs This function block has no input sockets. ## 📤 Outputs `Boolean` Output socket This outputs the current TRUE/FALSE value selected by the control. ## 🕹️ Controls `Switch` A two-position toggle labeled TRUE / FALSE. Flip it to set the output boolean value. ## 🎯 Features * Simple manual boolean generator for controlling logic flow. * Lightweight and immediate: changes propagate to connected blocks when toggled. * Useful for testing or manual overrides during setup and debugging. ## 📝 How to use * Place the `Logic Input` block in your scenario where you need a manual TRUE/FALSE signal. * Flip the `Switch` to TRUE to send an active signal, or to FALSE to send an inactive signal. * Connect the output to downstream blocks that accept a boolean/check input to control actions, triggers or gating behaviour. ## 📊 Behaviour when running When the scenario runs, the block continually outputs the current state of the `Switch` as a boolean value. Changing the switch updates the output immediately. ## 💡 Tips and Tricks * Combine the `Logic Input` output with logic blocks like `And`, `Or`, or `Not` to build more complex conditions. * Use `Rising Edge` or `Edge Rising` if you need a single trigger when the switch changes from FALSE to TRUE. * Use `ON Delay` or `OFF Delay` to add timed debounce or hold behaviour to the boolean signal. * Send the boolean to `Led Output` or `Record Video` (as a record trigger) to manually control visual indicators or recordings. * For passing the boolean value across separate parts of a scenario, use `Tag To` / `Tag From` or `Data Write Local` / `Data Read Local`. ## 🛠️ Troubleshooting * If downstream blocks do not respond, check that they accept a boolean/check input and that connections are valid. * If you need a one-shot trigger but get repeated activations, use `Rising Edge` to convert the steady TRUE into a single pulse. --- # 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.
