For the Arduino switch case code, the OR expression is implied by omission of the break statement. If you leave out the break statement, the flow of operation is for execution of the code in the next case statement. This continues until a break statement is encountered....

Demonstrates the use of a switch statement. The switch statement allows you to choose from among a set of discrete values of a variable. It's like a series of if statements. To see this sketch in action, but the board and sensor in a well-lit room, open the serial monitor, and and ...

and debugger from arduino says me error, like: 75:1: error: expected unqualified-id before 'switch' Can somebody explain or correct the mistake? And why it happens? May 4, 2015 at 6:41pm Gamer2015(810) your function loop endsd before the switch statement so switch is in no function....
–There is a watchdog timer in the ESP8266 that will reset the processor if you keep it busy too long. More on that in a future posting. Put lots of yield() or delay(0) statement in your program to keep this from happening. Note, delays with values greater than zero (delay(10) ...
Run the sketch and let it run for 30 seconds or so. You should never see the “Arduino Rebooted” message again after reboot. Then, comment out the RESETWATCHDOG statement like this: // #define RESETWATCHDOG Now when you run the sketch, if your WatchDog is working, then you should se...
