It's a basic countdown timer that should break when an input goes LOW. You can make the program exit a loop even while the condition is true with the break keyword. The while action executes a block until a given condition evaluates to false. If (Serial.I'm having trouble getting my while() loop to break. connection and should not break with the MQTT server being offline. In general, I have a 7-segment display that will act as an up counter when the condition is 01, down counter when the condition is 10, 00 for reset to zero, and 11 for stop (pause in that number). I suppose it depends how quickly you want to react to a change in alarmStop.
#Arduino while loop break code#
Actually the posted code in the question reads alarmStop multiple times which is a bit alarming (no pun intended). When attempting this various ways, the for loop within the function seems to blink the LED 10+ times and totally ignores my keystroke '2' to break the loop and is now. 1 Im not new to the programming world, but for last 2 weeks Im working with Arduino C++. Nested while loop Nested for loop Mixed type of nested loop Break and continue statement. at 11:01 Well it should be & AlarmState 0 to match the original post, but yes, that is another way. Int count = 0 // placeholder for incrementing during debugging of loops I was under the impression that I could use a while loop within 'void loop()' and call in a function which also contains a loop, then be able to break it from the while loop.
#Arduino while loop break serial#
Int ledPIN = 13 // sets up onboard LED on Arduino located near PIN13Ĭhar rx_byte = 0 // variable to hold serial input from console If you want to break out of the while loop when buttonState equals HIGH then you must read buttonPin inside the while loop, which you don't at the moment. Using serial from the Arduino to my PC, the below "Example 1" code, can break out of a local loop successfully (and immediately) when the Arduino received keyboard input with key "2". the simplest fix is to just add a 500ms delay before the break statement. The answers I have received there have been helpful but something is still puzzling me. Using serial from the Arduino to my PC, the below 'Example 1' code, can break out of a local loop successfully (and immediately) when the Arduino received keyboard input with key '2'. once it breaks, it will immediately take another reading, and enter settings () again after the 500ms delay.
I have a similar post, here, that I've decided to do something with the Arduino onboard LED, to isolate it from the NeoPixels Library and it is giving me the same issue.
#Arduino while loop break how to#
I am trying to figure out how to break out of a loop if it is being called from a function.
