 While sweeping, the Run button ({{learn:instrumentation:tutorials:waveforms-buttons:waveforms-run.png?nolink}}) changes to Stop ({{learn:instrumentation:tutorials:waveforms-buttons:waveforms-stop.png?nolink}}). Click Stop to stop outputting analog voltages, and to stop capturing data on the analog input pins.
