Hi: I'm trying to use a momentary contact pushbutton to generate a click for about 1/10 of a second when the LED is on. There should be no click when the LED is off. The LED part works fine but I get nothing out of the tone function. Without the toggle code the system works fine. Can you help w…

Alto777, it works. Thanks to your patience, tutoring and cajoling. Thanks. Here is the code. int LEDState = LOW; int LEDPin = LED_BUILTIN; int buttonPin = 12; int buttonNew; int buttonOld = 1; // input_pullup are normaly high int dt = 100; int buzzerPin = 6; int i; // Generally, you should …

Hello alto777. Done and happy for present. Are you talking about employing interrupts? The button is sluggish. Thanks so much for your help. My wife likes it and I guess that is the mark of success.

Hi alto777: I've reviewed the code and see that they are using the millis() line of instructions. I'll give it a go. I see that you are removing the delay() times as they are the inactive times when if you needed an event you would have to wait for the delays to end. Thanks again. Bob

[image] StAugustine: Are you talking about employing interrupts? No, def not. You won't need (shouldn't even think about) interrupts for this. They are so rarely appropriate and will be there when they are the solution: then will be time enough for what some might argue is the deeper waters. …

Hi alto777: I'm going to try to transition to the millis() concept. what is the purpose of counter ++ in the code that you showed me? Have a good day. Bob

[image] StAugustine: what is the purpose of counter ++ It's just so that as the sketch spams the serial output window with endless and frequent do this stuff here! lines that demonstrate that anything in the doIt block is getting regular attention (that would be beeping and blinking) each lin…

Hi Alto777: This is my latest small move to get the button and buzzer to work. I hope to add a bit of code each day. bob [6493C48CA6C1403F86688D5B6A588C5A.png]

int LEDState = 0; int LEDPin = LED_BUILTIN; int buttonPin = 12; int buttonNew; int buttonOld = 1; // input_pullup are normaly high int dt = 100; int buzzerPin = 7; int i; void setup() { Serial.begin(9600); pinMode(LEDPin, OUTPUT); pinMode(buttonPin, INPUT_PULLUP); } void loop() { static…

Alto777, I'm stuck. I don't see how to make the tone function work using the millis concepts. I have the LED working as the following code will show but it does not translate to the tone function repeating. Any suggestions? int LEDState = LOW; int LEDPin = LED_BUILTIN; int buttonPin = 12; int bu…

That is not "blink without delay"! Have you experimented with or studied any example of BWOD to get the idea of how it works? Do if you haven't, google: arduino blink without delay I will now literally cut and paste a random "blink without delay" from the internet into your sketch. I am currently …
