Learn how to use the delayMicroseconds function in Arduino for precise timing control in your projects. Perfect for beginners and experienced users alike, discover how to enhance your Arduino programming skills with effective timing control. Each microsecond is a millionth of a second i. Jan 23, 2020 · As a part of my project I need to generate 10 microseconds pulses with 10 milliseconds intervals. 1/1e6 seconds. For an Arduino Uno the basic instruction takes 1/16e6 or Mar 4, 2025 · Learn how to add delays in microseconds in Arduino using the delayMicroseconds() and micros() functions. Automatically handles micros() and millis() overflows / wrap around special cases. e. See examples of blinking LEDs, generating pulses, and adding jitter with delayMicroseconds (). For delays longer than a few thousand microseconds, you Nov 1, 2023 · Arduino provides a variety of functions for measuring and pausing your code execution, enabling you to precisely control timing in your sketches and build complex projects. We cannot assure that delayMicroseconds will perform precisely for smaller delay-times. And that was why I investigate this whole situation. Arduino Delay nanoseconds This is too small a delay for a microcontroller. " | | | delayMicroseconds () Description Pauses the program for the amount of time (in microseconds) specified as parameter. the value returned is always a multiple of four). Duemilanove and Nano), this function has a resolution of four microseconds (i. Learn how to use delayMicroseconds () to pause the program for a specified number of microseconds. Learn delayMicroseconds() example code, reference, definition. Oct 19, 2025 · Learn how to use delayMicroseconds() in Arduino for precise microsecond-level timing, pulses, and fast signal control. To get the 10us pulse width I needed to use 8us argument for delayMicroseconds function, but the actual problem is that randomly but pretty often (roughly 10% of the time) the pulse width jumps May 17, 2024 · Browse through hundreds of tutorials, datasheets, guides and other technical documentation to get started with Arduino products. Apr 22, 2017 · As explained in the previous answers, your actual is not the accuracy of delayMicroseconds(), but rather the resolution of micros(). Additionally, in the resources section of this site, it says: "This function works very accurately in the range 3 . Nov 1, 2023 · Learn how to use delayMicroseconds () to control execution for microseconds, enabling fine-grained timing for sensors, servos, signals, and more. What is Arduino delayMicroseconds(). I was using a separate Arduino Micro and a simplest code with delayMicroseconds() and delay() functions. Currently, the largest value that will produce an accurate delay is 16383. 125); does exactly what it says. Learn how to use the Arduino delayMicroseconds () function to generate very short time delays in microseconds and measure its accuracy. Explore examples and best practices. The Reason I am posting on here is to share this test Feb 21, 2019 · I have been working on an LED controller that uses a Return-to-zero protocol that requires me to send high and low signals at delays of 0. Pauses the program for the amount of time (in microseconds) specified by the parameter. Basically, I found out that delayMicroseconds(x) delays (on Arduino UNO, 16MHz) 7 Clock cycles for (x = 0, 1) 14 Clock cycles Short for (x >= 2) I noticed a too quick delay on 'x = 2' case. How to use delayMicroseconds() Function with Arduino. g. Jun 5, 2025 · Browse through hundreds of tutorials, datasheets, guides and other technical documentation to get started with Arduino products. Arduino Delay microseconds Another function you can use delayMicroseconds () which again takes a parameter but this time representing micro seconds. I noticed that the delayMicroseconds() only accepts whole numbers meaning, it won't allow me to create 0. " The docs for micros() says " On 16 MHz Arduino boards (e. Aug 2, 2022 · If you are doing a continuous use project, don't use millis() or micros(), or delay() or even delayMicroseconds() in your project, because the variable will experience a count reset (overflow), instead, use some timer or operating system. This could change in future Arduino releases. Feb 2, 2018 · BLOG_POST I highly Recommend reading my Blog Post above, there are graphs & Program & everything. One of the most useful but overlooked of these is delayMicroseconds (). Learn how to use the delayMicroseconds () function in Arduino to pause for a specific number of microseconds.
