I have declared different pins so that they operate independently but cannot work out how to make a loop in a loop. I have read and viewed video's about this subject for days, but I have a hard time making it work. However, it is all a moot point on the Arduino, as there is only one process - the main loop(). However, I have a bit of C++ programming background and, reading the mythical "several things at the same time" thread (thanks Robin2, very useful!) I noticed overflows are never mentioned (plenty of indenting style and if vs. I've arbitrarily changed around the items within the void to see if it affected the functionality of the program but it still runs as intended. I tried making an integer and extract 1 after a 1000 delay, but it freezes the whole program, and whenever I update The SoftwareSerial library allows serial communication on other digital pins of an Arduino board, using software to replicate the functionality (hence the name "SoftwareSerial"). // / respective targets at very close to the same time. Sep 8, 2020 · Gives you the ability to run as many things as you want at the same time. Nov 10, 2020 · It's a long time since I wrote and tested the Tutorial code.

I want to blink LED's like a police car. If that means this, then it says in the comments: Jul 5, 2018 · Hi, I need some help combining some loops, creating a Cricket scoreboard using 74HC595N's and 7 segment displays. If so, do the next step. On D2 I have a pin connected to an IR obstacle avoidance sensor to measure the RPM of a wheel. Not at the same time. both For example: i have readers 0 and readers 1, and two variables count0 and count1, remember the readers faces each others, so i put one tag in the middle of reader0 and reader1, if the reader 0 scan the tag, count0 will increase to 1 and if reader 1 scan the tag in the SAME TIME it wouldn’t be counting because the reader 0 has scan that tag. Perhaps just change your title to "Question about several things at the same time" Thank you. Time is a library that provides timekeeping functionality for Arduino. Jan 5, 2020 · Enable multiple USB in Simhub [Optional, recommended for a first setup] In the multi USB settings remove all the previously detected devices : Press Scan now, and wait for the button to unlock, all the detected devices should appear in the list. Which when differenced with millis() is either negative while it is still in the future, or positive once the time has passed. The delay() function prevents the Arduino from doing anything else until the period expires. Those different voltage levels connected to the same I2C bus is not nice. println(a,b,c) it does not show the correct result Aug 11, 2011 · Hi all, first time here =) I'm EXTREMELLY noob with Arduino, just learning the basics by now so, please, sorry for stupid questions but anyway, here is my problem: I'm trying to make a simple thing here: With 2 speakers, I want to make one of them play a note With a potenciometer, I'll control the 2nd speaker and, when you get the same note of the 1st speaker, a LED lights. Nov 28, 2012 · Been playing with Arduino, but suspect this may not be possible: I want to have one led flicker, two motors doing different things, and a servo doing something else all at the same time. True parallel execution is impossible on an 8 bit Arduino, of course, but these task macros allow to write cooperative tasks easily. I'm trying to get an idea of what the best way to structure a sketch is, which needs to do several things at the same time. As this is only the beginning and will be extended with multiple load cells and steppers, I want to use millis() instead of delay. Jan 26, 2017 · On Arduino (and on most other micro controllers for what it matters) you CANNOT do two things at the exact same time, so forget about running two loops in principle. It is not clear in the datasheet, but the HX711 is free running at 80Hz. I used to program in C++ about 25 years ago in college. How would i add a second or third dot that could be moving along the strip at a different speed as the other(s). 2V). // Arduino variable type word can be 0 to 65535, easy to type. So I have a code that takes Dallas temperature sensor reading and uploads the value to internet server (https://m2x. Every task looks like this: taskBegin(); //execute following code without blocking other tasks Feb 15, 2021 · First of all, thank you for taking the time to read this. One mistake it makes is here: "The superloop architecture also provides excellent responsiveness to external events. All encoders are connected in one arduino mega2560, and I use int0, int1, int2 pins for each encoder. Will that code actually use more cpu cycles than simply reading the sensor. 1. println(a) Serial. ino // An expansion of the BlinkWithoutDelay concept to illustrate how a script // can appear to do several things at the same time // this sketch does the following // it blinks the onboard LED (as in the blinkWithoutDelay sketch) // it blinks two external LEDs (LedA and LedB) that are connected to pins 12 and 11. one will work the other wont. Such as headlights that go back and forth and red and blue lights that blink fast and then even a set of strobes that blink fast as well, but not as fast as the red and blue's but faster than the headlights. What you can do is: run two separate piece of code one after the other, fast enough that they look to be running in parallel or run one continuously and run the other when an event occurs. UDP is a lossy protocol and it might be possible to get things to work if you keep the sample rate very low. By dedicating the foreground loop to time Jan 20, 2021 · The question is about doing multiple code-things at the same time. In both cases you are doing non-blocking programming.

Jun 21, 2018 · Hi guys, I'm kinda new to Arduino, so apologize my little knowlige about the things related to Arduino. But as soon we use more, calling the ‘is_ready’ function becomes asynchronous. Nov 25, 2014 · If you want to have more than one thing controlled by time then you MUST stop using the delay() function and use millis() for timing. Nov 5, 2024 · I don't think there's any point in arguing. Apr 29, 2021 · A still camera is mounted outside the projector and is focused on the film gate. begin(0); mcp2. One of the strengths of MQTT is that a device can subscribe (or publish) to multiple topics. I have done zero programing since then. What I'm trying to accomplish is to have 2 LEDs blinking (alternating) while that happens I can control a servo to move back and forth based on my potentiometer. That thread is definitely helpful for people who want to be super close to the metal, but at the same time, what if there's an easier way that usually gives us better performance? I wanted to share how the exact same effects can be achieved using FreeRTOS, with less code and more Also see Arduino For Beginners – Next Steps How to write Timers and Delays in Arduino Safe Arduino String Processing for Beginners Simple Arduino Libraries for Beginners Simple Multi-tasking in Arduino (this one) Arduino Serial I/O for the Real World. Jul 6, 2011 · Hello Forum It has been a while since I have messed with my Arduino and i have some free time but I am still stuck on an old problem and I hope someone can help. But they switch so fast, you'll never notice. begin(1); mcp3. Write better code with AI Code review.
