May 14, 2011 · void setup() { Serial.begin(9600); pinMode(13, OUTPUT); pinMode(10, OUTPUT); } void loop() { int sensorValue = analogRead(A0); int sensorValue2 = analogRead(A2); int totaal[0]; if ( sensorValue < 100 ) { totaal[0] ++; delay(2000); } else { } if ( totaal[0] = 4 ) { digitalWrite(13, HIGH); Serial.println("test") } Serial.println(totaal[0],DEC); }

Jan 4, 2018 · Playing off @CrossRoads ' arrays, you could (I think) eliminate one whole array and just do a linear search of a single array containing all R_in compares. This isn't tested, just quickly thrown together. If time's an issue a better search algorithm could be used.

Dec 6, 2016 · I wanted to compare array element in if condititions. When i got some value in array, i want to check next one and print msg. I can get first valus successfully but next one is successfull when i increase the array. Serial.begin(9600); // hang in this loop until we either get 20 bytes of data or 1 second. // has gone by.

Oct 2, 2024 · There's also the else-if, where you can check a second condition if the first is false: 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 …

May 14, 2024 · if... else allows greater control over the flow of code than the basic if statement, by allowing multiple tests to be grouped. An else clause (if at all exists) will be executed if the condition in the if statement results in false. The else can proceed another if test, so that multiple, mutually exclusive tests can be run at the same time.

How to use else with Arduino. Learn else example code, reference, definition. The if...else allows greater control over the flow of code than the basic if statement, by allowing multiple tests to be grouped.

Jul 16, 2015 · Now you can use a for loop to iterate though that list and turn on the LED you want: for (uint8_t i = 0; i < 8; i++) { if (i == value) { digitalWrite(ledPin[i], HIGH); } else { digitalWrite(ledPin[i], LOW); } }

May 16, 2018 · My code for Arduino is: if (a == 0) { int led_pin [4] = {3, 4, 5, 6}; else{ int led_pin [2] = {4, 5, 6, 9}; for (int i = 0; i <= 7; i++){ digitalWrite(led_pin[i], HIGH); How to declared array or …

Dec 20, 2022 · In this lesson we learn about IF, ESLE and ELSE IF statements. then we learn how to define an array, how to fill it up, how to read all elements of array and how to update the values of an array. Then we learn the advantages of array in …

May 28, 2015 · You have to iterate through the array and determine if the value is in the array. bool hitAlien = false; for(byte a=0; a<ALIEN_COUNT; a++) { if(xb == xAliens[a] && yb = yAliens[a]) { hitAlien = true; break; } } if(hitAlien) { // do something }
