![]() And, of course, it is easy to add else statements and Serial.print() statements, to confirm that the left, right, top, and bottom tests are, or are not, successful, to see if the test results match your expectations. I need help with blinking 4 of the LEDs continuously with 100ms pause in case 1. if you want to convert if statement to Switch ,i.e i am assuming that you want to improve the readability of the code ,you can use if statement in loop and put switch in a function. In each case statement, there will be different LED functions. But, for more than 2 buttons, nested if statements are far easier to deal with. The overview of my code is that I want a toggle button to be pushed and each button push will move the code to the next case statement. ![]() Simply put, depending on whether or not sensorA is high, it will activate 2 different switch case loops. The encoder and the DC gearmotor are connected to a H-bridge module. Hmmm, words are not helping all that much. I am trying to read the revolutions of a DC gearmotor with a rotary encoder on top. the following code is returning true Via serial terminal by confirming touch coordinates the value page is set in the beginning of the code to 0 until main screen loads then it switches to 1 (again. i am using a switch case with an if statement inside to help with touch screen touches. ![]() Two more tests to confirm the possibility of being 1 or 3 or 2 or 4. switch case with an if statement not working when true. That is only what you think it should do. Therefore using this two if statements I actually confined to speed. CodingCarnage: LED changes depending on what you write to serial, 0 is for it to be OFF, 1 is for it be ON, and 2 is for BLINK. Two more tests, and you know that it could be buttons 2 or 4. In my case, the motors were not able to move if the value of the PWM signal was below 70. So, two tests, and you know that the press could be in one of two buttons. Similarly, the p.x value will be less than some value for the press to be in 1 or 3. Hello im newbie here.i wanna ask bout how to write if.conditional inside switch case.i have a project bout servo and voice recognition, servo already worked with voice recog but.i want the servo to stopped when i pressed additional button.and i figured itll need if statement but it cant seem to work. If buttons 1 and 2 are on the same row, and buttons 3 and 4 are on the next row, and lined up, then you only need to test that p.x is greater than the left edge of one button to test that the press is in either button 1 or button 3. You don't actually need 16 if statements for 4 buttons. I have put the code in the case statements, I have put the code within loops within the case statements, I have done everything I can think of. This tutorial shows you how to use switch to turn turn one of several different LEDs located on a type of. You can have 4 ugly, complex, redundant if statements, or you can have 16 simple if statements. Now, why might this be better? Suppose you have 4 buttons. It's far easier to debug code that involves multiple if tests if you use multiple if statements.
