#Arduino else if command code

delay(1000) and delay(500), and you can't check for button presses while the program is waiting. Sometimes we think our program has to do something and break out of execution, but upon careful examination, we conclude that it can finish one loop interation and then quit.Ĭould you tell us what's done inside the loops, so we can make sure what's needed?Įdit: As I suspected, the problem with your program is that your delay intervals are too long, e.g. I don't think using interrupts will help, since I don't know how I could use them in my problem.Īre you sure you need to exit at ANY time wherever the execution pointer is? Normally, you could just check the button press at the end of the while and for loops and call return when it is pressed. It allows you to make something happen or not, depending on whether a given condition is true or not. I have to press it multiple times, sometimes two or sometimes even more times. The if () statement is the most basic of all programming control structures. In practice I still can't get it to stop blinking every time 5th button is pressed again. That is how it is supposed to work in theory. If at any time during blinking LEDs 5th button is pressed again, Arduino stops the blinking and again waits for the presses from first four buttons. An else clause (if at all exists) will be executed if the condition in the if statement results in false.

Then based on that what is stored I determine which pin/LED will light up. Description The if else allows greater control over the flow of code than the basic if statement, by allowing multiple tests to be grouped. When 5th button is pressed, we brake out and store last known place in array in which value was stored and set the place counter to zero so when starting again, Arduino stores values in the first place of array. If it was store it in an array and if not keep 'looking'. If ((val = 1) || (val = 2) || (val = 3) || (val = 4)) loop, while the 5th button isn't pressed, Arduino is 'looking' if any of first four buttons was pressed. Multiple If/Else if Statements Using Arduino Programming Questions thatproduction25 April 29, 2022, 6:24pm 1 Hello All New to Arduino and programming, gotten far but am hung up on the last thing I would like to get working. Else if (c>169 & c209 & c247 & c280 & c 1015) b = 0 Įlse if (c > 70 & c 122 & c 169 & c 209 & c 247 & c 280 & c < 291) b = 6 Look at the Arduino site reference page and the description of the if.else statement under the Structure section.
