Right now it runs the first loop then after it is finish it runs the next loop i need both loops to run at the same time Here is my code: int LED1 = 13; int LED2 = 12; int LED3 = 8; void setup() { pinMode(LED1,OUTPUT); pinMode(LED2, OUTPUT); pinMode(LED3, OUTPUT); for (int i=0; i<=99; i++){…

[image] lhacker: Right now it runs the first loop then after it is finish it runs the next loop i need both loops to run at the same time WE all know that is not going to happen, so you need to rework your logic.

your first loop 100 times LED1 switches the LED ON/OFF 200 / 200 milliceonds. this means periodtime 0,4 seconds = frequency 1 / period = 2,5 Hz doing this 100 times need 0,4 * 100 = 40 seconds LED2/3 switch on/off 500/500 millicesonds This means peiodtime 1 second frequency 1 / periodtime = 1…

Hi , see in this image how the LEDs will behave. [LED_Time]

Looks like the common interval is 100 milliseconds. unsigned long LastIntervalTime = 0; unsigned long IntervalCount = 0; void blinker() { unsigned long currentTime = millis(); if (currentTime - LastIntervalTime < 100) return; LastIntervalTime = currentTime; bool On1 = ((IntervalCo…

Hi Ihacker, welcome to the Arduino-forum. There are a few things to learn about how to use this forum You should post code as a code-section. Read the link at the bottom to learn two ways how this can be done very quickly. here is a commented code that I think is easier to understand. const byt…

[image] DaveX: Why is periodStartTime = currentMillis; preferable to periodStartTime += TimePeriod; ? As long as there is no chance of what is discussed here, += TimePeriod can be used. [image] Blink Without Delay problem. Warning. Programming Questions Warning to …

[image] LarryD: Note: If it is important to your sketch, periodStartTime = currentMillis; keeps subsequent TIMERs all referenced to the same time. @LarryD I'm unsure what you mean with that. If you want to use the function TimePeriodIsOver for timing a second thing you simply use a second …

An interesting discussion at that link. I am in the “it depends what you want” camp. I will admit to having been surprised at a flurry of activity at loop rate, but upon analysis I saw what was happening and made a note to choose based on the circumstances. If the missed events, so to speak, were …
