You already understand why you should not use delay() andĪre familiar with Arduino, the importance of using unsigned longs, ThereĪre also examples of single-shot and repeating timers. The second is an example of code the works and the third is anĮxample of using the millisDelay library to simplify the code. The first one is an example of how you should NOT write theĬode. Number of simple sketches each of which turn a Led on when theĪrduino board is powered up (or reset) and then 10sec later turns it Multi-tasking in Arduino covers all the other necessary steps. This is the first step toĪchieving simple multi-tasking on any Arduino board.
Step by step way how to replace Arduino delay() withĪ non-blocking version that allows you code to continue to run while However replacing delays requires some care. Your system to be stuck while waiting for the delay to expire. Install the SafeString library and jump to PinFlasher
You just want to flash an output pin On and Off at a given rate, Use the millisDelay library, install the SafeString library and jump If you are just looking for info on how to Serial I/O for the Real World Introduction To write Timers and Delays in Arduino (this one) IsFinished() to justFinished(), as it only returns TRUE once just Multi-tasking in Arduino covers all the other necessary Step to achieving simple multi-tasking on any Arduino board. The millisDelay class is now part of the SafeString library V3+.ĭownload SafeString from the Arduino Library manager or from its zipĥth Sept 2019 update: Removing delay() calls is the first May 2021 update: re-wrote examples as 'tasks' from SimpleĪnd Sequencing examples and Delayed execution PinFlasher class and example (included in NSWĮxamples – Single-Shot Delays and Repeating TimersĮxecution until condition has been true for X secs
