Button buzzer arduino how to#

I have changed the code and got the buzzer beeping on and off but how can I make it to repeat only 4 times and not forever. Oh I got parts of the code from other websites and forgot to change the comments. However, when I hold the buzzer down, it preforms as desired. If buzzerOn() sets up to call buzzerOff() later, shouldn't buzzerOff() set up to call buzzerOn() later? When I do this and I push button B, the buzzer only does the buzzer sound for 1 second. The use of the SimpleTimer class is, too.ĭoes the class keep track of how many times to do something? Why would it? If it doesn't, you need to, and you need to stop doing it when it has been done the required number of times.

Which of those arguments means pulse a relay? Which of those arguments means 500 milliseconds? Which of those arguments means three times? PaulS: tTimer(1000, buzzerOn, 4) // Pulse Relay ON routine three times in 500ms I have considered this but I thought simple timer is less complicated.

It will show you how to flash an LED and not use delays, so not blocking your code. Look in the IDE Examples for 'Blink without Delay' tTimer(1000, buzzerOn, 4) // Pulse Relay ON routine three times in 500ms the loop function runs over and over again forever After that, I can press my button again and the whole thing starts from the beginning. Basically I have these LEDs that light up in a row with every time I press my button and once the last LED lights up, the buzzer should play its melody. tTimer(1000, buzzerOff, 1) // turn off after 1min After that it should immediately stop, without looping everything until I press the button again. initialize digital pin LED_BUILTIN as an output. the setup function runs once when you press reset or power the board I have studied the Simple Timer Library but couldnt understand. I can t use delay in the final project because of the timing.

But the led just comes and and does not blink. It is supposed to turns on the buzzer on and off 4 times every time the sensor goes LOW. Now my problem is that it is not working as I want it to.

I am working on a project that needs to beep 4 times to notify a task is done.
