![]() ![]() ![]() The button press is recognized, but it executes the code twice in the if statement.in this case the led is on for 4 seconds. Now i created two separate functions, trying to do waht you mentioned in the first post with "several things at a time" and "Using millis() for timing. To put it simply, the millis function makes use of an internal counter within the ATmega microcontroller at the heart of your Arduino. ![]() What i should have mentioned before is that there is nothing displayed on the display or atleast not readable for the human eye.Īnyways the problem with the random chars is gone.īut the display is not able to display any text because of the missing delay right? #include PreviousMillis = previousMillis + interval #include ĮlapsedMillis = currentMillis - previousMillis I plan to add additional 'button pins' for. Several of these need to eventually be running, most likely three, so using delay() won't work. It is intended to power a relay and offer a visual cue to when the cycle is over. I tried to do the interval with millis instead of delay.īut I still didn't get it because this just runs through everything until the display gives up and just spits out random chars. I am trying to use the millis() function to turn on a pin for a specified interval then turn off and turn on a second pin. To detect a short and long button press using millis can give your project more functionality without adding more buttons. I think the solution above is only good, when you run this function only one time. In this tutorial Ill teach you how to detect whether a button is being short or long pressed using millis (). For the search you can use: button debouncing microcontroller or button state change microcontroller. TimersSize = sizeof(timers)/sizeof(timers) 1,553 1 12 17 asked at 14:50 Patrick Bucher 143 1 1 5 You can ask google how they solve this problem in c with microcontrollers. I looked through several forum posts and i think using millis() would be the solution, but I am somehow not able to wrap my head around that damn millis() "thing". So far i managed to loop through the char array and show the values on the lcd, but I am not able to do the job with the button. What i would like to do is, having an lcd screen that shows the user some predefined values(timers) and give him the possibility to choose the wanted one with a button press. ![]()
