Web(Seeeduino with ATMega168) Time for digitalWrite (): 3804 Time for true c command: 348 So each style turned on the pin 500 times and turned it back off 500 times. digitalWrite () took 3804 microseconds, while the true c commands took just 348 microseconds. The true c commands are 10 times faster than the digitalWrite ()! WebOnce setup() is finished, Arduino calls the loop() method over and over again. This is where most of you code goes, reading sensors sending output etc. In the sketch above, the first time loop() ... Usually the delays these introduce are small but they can add up so I suggest you add a monitor at the top of your loop() to check how quickly it runs.
