An "if" statement has the general form of: if (condition) light_led1; else turn_off_led1; The "else" part is optional. "Condition" is boolean term using "true" or "false" A "true" condition lights LED1, a "false" condition turns LED1 OFF. The Arduino compiler defines "true" ...
(buttonPin); // check if the input is LOW, this will indicate // whether the button is pressed if (val == 0) { // if the button is pressed, then turn the light on digitalWrite(lightPin, HIGH); // turn LED ON // otherwise, turn the light on } else { digitalWrite(lightPin, ...
The upshot is that you can write very confusing code, but it is powerful - use it sparingly if at all!. Does a for loop block Arduino? Yes: Once you start a for loop you are stuck in that for-loop unless... ...unless you break out of it! See the break statement above. ...
First, we use the functiondisplayAnimate()in anifstatement. This function animates the display using the currently specified text and animation parameters and returns true when the animation has finished. When the animation has finished, we reset the display with the functiondisplayReset()so the t...

If there is no instruction not to stop (or jump somewhere else) it just keeps going until it runs out of memory.In Arduino code, the loop() construct contains an infinite while loop.An infinite while loop is just a while loop with the conditional set to true. As with the normal loop...
