Arduino delay wait1/18/2024 ![]() Serial. (I know I could probably code the colours far more efficiently but i'm only just beginning so go easy on me ) int rPin = 6 The code for the 'while' loop waiting in serial input is lines 28 to 70 I did not write all the original code (open source) below and have had some trouble understanding timer interrupts, etc. Im currently using an Arduino Nano to create a 40kHz signal to a set up of transducers via an H bridge driver board. I have the code working to constantly cycle the colours on it's own, but when I paste it into a 'while' function that is waiting for serial input (Serial.available() = 0) it runs once and then waits for input but doesn't cycle again. Hi, Im a newbie on here and have a basic understanding of programming an Arduino Uno and Nano. Instead of using a FOR loop, you would increment the global variable and use a range check to detect whether you have completed each sequence. ![]() The NoDelay library is used as a easy interface for using the built. I have the bulk of the code working, the only thing stumping me is how to get the LED to cycle through the spectrum whilst waiting on a serial input. The way I would do that is make your loop counters global variables and use the blink without delay approach to determine when it was time to carry out the next action. Arduino library to make use of the Millis funtion for non Blocking Delays. It's basically an RGB LED that will change colour to match an input on the serial monitor. The delay () function allows you to pause the execution of your Arduino program for a specified period. 4294967295ms (232-1) or 49 days, after which the timer will catch up to the value of startMillis. unsigned long startMillis millis () while (millis () - startMillis < LONGDELAYMS) This will delay up to approx. in case of command Backlog Power1 OFF Delay 600 Power1 ON the usage of an additional Backlog command without any argument within the delay time of 1 minute. I'm currently trying to do my first simple project written & designed by myself from the ground up. The real time clock method is the most accurate way but otherwise use millis.
