The companion tutorial Simple Multi-tasking in Arduino covers all the other necessary steps. This is the first step to achieving simple multi-tasking on any Arduino board.

This page explains in a step by step way how to replace Arduino delay() with a non-blocking version that allows you code to continue to run while waiting for the delay to time out. However replacing delays requires some care. Using delay() causes your system to be stuck while waiting for the delay to expire. If you are just looking for info on how to use the millisDelay library jump to Using the millisDelay library (Step 4) If you just want to flash an output pin On and Off at a given rate jump to PinFlasher (Step 6) Added Freeze/Pause delay exampleĪlso see Arduino For Beginners – Next Steps How to write Timers and Delays in Arduino (this one) Safe Arduino String Processing for Beginners Simple Arduino Libraries for Beginners Simple Multi-tasking in Arduino Arduino Serial I/O for the Real World The instructable Simple Multi-tasking in Arduino on Any Board covers all the other necessary steps.ĥth May 2019 update: Renamed isFinished() to justFinished(), as it only returns TRUE once just after the delay finishes.
Download SafeString from the Arduino Library manager or from its zip fileĥth Sept 2019 update: Removing delay() calls is the first step to achieving simple multi-tasking on any Arduino board.
20th Dec 2021 update: added PinFlasher class and example (included in SafeString library V4.1.13+)Ħth Jan 2020 update: The millisDelay class is now part of the SafeString library V3+.
