![]() ![]() 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. Imagine that, using your electric scooter to flip the switch on your mundane sandwich. But, for more than 2 buttons, nested if statements are far easier to deal with. Posted in Arduino Hacks, Transportation Hacks Tagged 18650, bms. Hmmm, words are not helping all that much. Two more tests to confirm the possibility of being 1 or 3 or 2 or 4. Within this block, you can define several actions. Two more tests, and you know that it could be buttons 2 or 4. With then, you tell ESPHome what should happen when the press happens. So, two tests, and you know that the press could be in one of two buttons. Therefore using this two if statements I actually confined to speed. Similarly, the p.x value will be less than some value for the press to be in 1 or 3. In my case, the motors were not able to move if the value of the PWM signal was below 70. 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. This time simplify the LED sequence functions using FOR control statements to achieve the required iterations Pin modes of each LED pins are to be iterated together using a FOR statement The circuit: LEDs connected from digital pin 4-11, all with respect to ground. 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. In this little 'project' im asked to have a analog sensor which is the potentiometer, regulating the tone of a piezo buzzer using five switch cases according to the analog reading. So i need help changing the if else statements into switch case statements as im new to coding in arduino and cant seem to get it to work. ![]() Templating with an If Statement to create a new senso the valuetemplate would not. Im new around here, and also new about the introduction to arduino and C. ![]() It's far easier to debug code that involves multiple if tests if you use multiple if statements. If you can feed your template sensors to Utility Meters and use the. ![]()
