![]() ![]() ![]() In this implementation, you use a variable increment to decide whether you have to go forward or backwards when increment is 1 the led to be colored are 0 -> 1 -> 2 -> (3)0 -> 1. LastMillisForBlink += millisBetweenBlinks ĬurrentLed = (currentLed + increment) % 3 So, if the value is different from the one I think it is I'll wait for some milliseconds if it is stable then I change the value I think it is.Īs for removing the delay, I think it is better to use an approach similar to the "blink without delay" sketch: if ((((uint16_t)currMillis) - lastMillisForBlink) >= millisBetweenBlinks) Increment = 2 // Go in the other direction If (((byte)currMillis) - lastMillisForButton) >= millisButtonDebounce)ĭebouncedValueOfButton = !debouncedValueOfButton In order to solve the bounces, you will have to wait some time to stabilize the signal: if (debouncedValueOfButton != (digitalRead(button_pin) = HIGH)) The first one is that delay functions should be avoided whenever possible, the other is that the switch bounces. In my opinion, there are two things I'd change. LukaUK: I am trying to make two neopixel 16 pixel rings flash like police sirens for a costume. ![]() Since only one led will be on, you can also use the following functions for Loop and show:Īnd it's even better to use constants: const int LED1 = 3 DeltaG July 24, 2018, 9:48pm 2 LukaUK: Hi all, I'm new to use Arduino's so go easy on me An opening sure to get you lots of extra hard time. But check in the Arduino examples to a debounce example for this problem and the program should work as expected. However, you cannot simply check for the button state. Void show(bool led1, bool led2, bool led3)ĬheckReverse will check the input button and returns true if the mode should be reversed. So the program will be something like (not tested): Initially this is true.Īn if statement will be used to change the order. The easiest is to use a 'mode', which is a boolean that keeps the state if it is blinking right, let's call it blinkToRight. It only goes from left to right and keeps repeating. The problem with this code is that it doesn't keep blinking if I release the push button. Now I am trying to modify this code so that whenever the system receives a High from the switch it reverses the order, so it should start blinking from right to left and keep blinking that way until I press the push button and then return to left to right. I am new to Arduino and I have written code that makes 3 LEDs blink while the push button is off, so the lights are blinking from left to right (1,0,0)(0,1,0)(0,0,1) and then repeat from left to right. ![]()
