![]() PinMode(led, OUTPUT) // initialize the digital pin as an output. int led = 13 unsigned long delayStart = 0 // the time the delay startedīool delayRunning = false // true if still waiting for delay to finish On the boards from the Arduino Portenta family this function has a resolution of one microsecond on all cores. This number will overflow (go back to zero), after approximately 70 minutes. Here is how NOT to code a delay in a sketch. Returns the number of microseconds since the Arduino board began running the current program. However replacing delays requires some care. This instructable is also on-line at How to code Timers and Delays in Arduino Step 1: How Not to Code a Delay in Arduino Using delay() causes your system to be stuck while waiting for the delay to expire. The millisDelay library provides functionality delays and timers, is simple to use and easy to understand for those new to Arduino. If you already understand why you should not use delay() and are familiar with Arduino, the importance of using unsigned longs, overflow, and unsigned subtraction, then you can just skip to Using the millisDelay library (Step 4) There are also examples of single-shot and repeating timers. i am totally new in programming, and i was always using the delay function, i really want to get that away from my programming. This function returns the number of milliseconds the current sketch has been running since the last reset. The second is an example of code the works and the third is an example of using the millisDelay library to simplify the code. The millis() function is one of the most powerful functions of the Arduino library. The first one is an example of how you should NOT write the code. Here are a number of simple sketches each of which turns a Led on when the Arduino board is powered up (or reset) and then 10sec later turns it off. This page explains in a step by step way how to replace Arduino delay() with a non-blocking version that allows your 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. In this guide, learn when, how, and why to use millis () instead of delay (). ![]() However, you can also use the millis () function. In the sketches included in that guide, the delay () function was used to create a pause in the program.
