12/8/2023 0 Comments Arduino while loop exitI gather you want to update if it's out by. You might have to put the while != statements outside the other while statement to make it work right.

Serial.println("no client connected, retrying") TEST START Inside the DO WHILE loop: i 0 Inside the DO WHILE loop: i 1 Inside the DO WHILE loop: i 2 Inside the DO WHILE loop: i 3 TEST END. Serial.println(thermocouple.readInternal()) if the command is exit, just terminate the self-defined function. inside the while () loop, use a code to check command. change all delay () function by using while () loop and millis () function. A while loop will loop continuously, and infinitely, until the expression inside the parenthesis, () becomes false. Please have a look and it would be great to have advice, thank you! #include Īdafruit_MAX31855 thermocouple(MAXCLK, MAXCS, MAXDO) ĭouble temp = thermocouple.readCelsius() I would like to recommend the following way: put all code inside 'if statement' to a self-defined function. My android app stops the reading in the app but cannot break the while loop in the arduino code. It also causes a recursion in your code, youre calling loop before the previous call to loop has finished. You cant return the value of a function that returns nothing. The value, -5, inside the if statement used for breaking is the value sent from my android app when i press an Off button from my android app. return loop() That line is pretty useless. But when my android app sends a value of 10(1 second), 100(5 seconds) or 200 (10 seconds), the while loop keeps looping despite placing a break inside the while loop. Right now my progress is only to display the temperature onto my android app. So really there are only 2 states: flashing the LED and debouncing the button.Īsk questions when you get stuck with it.Hi everybody, I am currently doing a temperature data logger using my android app to control the arduino yun via WiFi. Only differ in the speed at which they flash the LED.ĭebounceToMedium, debounceToFast, debounceToSlowĭebounce the button and then move on to the next flashing state when the button is released. I don't expect you to get it straight away. In most computer programming languages, a while loop is a control flow statement that allows code to be executed repeatedly based on a given Boolean. Here is a 6 state state machine that flashes the built in LED at 3 different speeds. on simple sketches like this I also add a delay(1) at the end of the loop, Ive had issues that this fixes when loop doesnt take any real time. The problem is, that I cannot access the keypad in the loop. Then I want to leave the loop and continue the program execution. The program must stay in this loop until all the parameters are set. In this loop I have to set some parameters. add serial prints and see where its getting stuck. So what I basically want to do, is to enter a loop with the press of a button. I have been at it for hours and would like some guidance if possible. If your while loops actually did something to change some state that would be different, but youre just doing the same thing over and over. I can break out of the while loop just using break after it without the button, but for some reason it will not work with the push button. The reset should return to the top of the loop where it says "Alarm Deactivated." In the wrong_pw function is where I am trying to break out of the while loop with the buttonState = HIGH. I am trying to have the number of wrong keypad entries (which is 2 in this case) need to have a reset that is done by a push button. This is my first post and I am fairly new to using the Arduino. Keypad keypad = Keypad(makeKeymap(kp), rowPins, colPins, ROWS, COLS) ĭelay(2000) //time for how long the security alarm is deactivated before user alert LiquidCrystal_I2C lcd(0x27,20,4) // set the LCD address to 0x27 for a 20 chars and 4 line display assign Arduino pins 9-2 for rows & columns
