void loop() { delay(100); if ( S1() ) digitalWrite(LED1, 1); else digitalWrite(LED1, 0); } Test 1 Note: true = 1; false = 0. Or should I say any value except 0 is TRUE. Note the code above. An "if" statement has the general form of: if (condition) light_led1; els...
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. ...
The setup statement is the first thing called in the Arduino application. As in a Processing application, this is where things that need to be initialized should be placed. For instance, if you’re going to use the Serial port for debugging your application, you’ll need to start the Seria...

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...
