 In this scenario, you will implement a classical "Hello World" application. For microcontrollers, the "Hello World" application is a blinking LED. Because we use remote observation via an integrated video camera stream, the proper LED frequency is at most 1 or 2Hz, depending on the connection quality. In this scenario, you will use blocking nested loops and manual calculation of the ticks needed to run them, to obtain precise ''delay'', as presented in the chapter [[..:..:..:arduinouno|]].\\\\ In this scenario, you will implement a classical "Hello World" application.

 **It does not flash**: Did you compile and upload to the device? Those are separate steps: it is not enough to just compile, but you also need to "flash" the MCU. Also, check your video stream if it "ticks" - the time embedded into the video stream should change. Your code may be working OK, but the video stream can be frozen, so you cannot see it working properly! **It does not flash**: Did you compile and upload to the device?

 +**I need a longer delay**: To obtain a delay function with a period of about 2.5s, you need to introduce a fourth loop (an outer loop) in the delay; 3 will not provide you enough ticks. Eventually, you can switch to 16-bit counters.
