4 kwi 2015 · If you use this range checking a lot you might put it in a function. bool inRange(int val, int minimum, int maximum) { return ((minimum <= val) && (val <= maximum)); } ... // example usage int x = analogRead(A0); if ( inRange(x, 0, 200) ) { ... } else { ...
20 sie 2017 · bool inRange(int val, int minimum, int maximum) {. return ((minimum <= val) && (val <= maximum)); } Paul_KD7HB August 20, 2017, 1:20am 2. The obvious error is you are trying to set an integer to a number with a decimal point. Look up the description and use of "integer" in the -learning- section of the forum. Paul.
17 lut 2014 · I've just started playing with Arduino and can't find an answer to what I suspect is a very simple programming problem (my apologies, I am a real newbie). My question, is there a way to create an IF statement that tests a range? i.e: If (sensorValue>0 and less than 50), do this...
28 lis 2019 · you should simply write code to compute the state necessary for each led based on the truth table and write out that state to the specific digital pin only once; you would not need so many if/else conditions and so many calls to the digitalWrite function either; by the way your code will also work fine if you update your assignments to ...
1 if (someCondition) {. 2. 3} else if (anotherCondition) {. 4. 5. 6} You'll use if statements all the time. The example below turns on an LED on pin 13 (the built-in LED on many Arduino boards) if the value read on an analog input goes above a certain threshold.
5 gru 2018 · What I want the program to do is to run the code if the condition (x==0 in this case) is true for 2 seconds. I find that the easiest way is to restart a timer every time the condition is false. If the timer reaches the desired interval then the condition has been true for that long:
15 maj 2017 · if (t.hour == 7 && t.min == 00 && moistureOneSensorValue >= 700) {. RelayOne(); RelayTwo(); } When moistureOneSensorValue is greater than or equal to 700 it means the soil is DRY, so when all conditions inside the if statement are true the relayOne and relayTwo functions will be called.
