Controlling Time with Arduino Delay

If you want to make your Arduino sleep for 1 minute, or for multiple minutes, then it’s quite easy. To achieve this, you need to use the `delay()` function, which expects a number of milliseconds as input. This means that if you think in seconds, you need to multiply the number by 1000 and get the value you need.

For instance, if you want your program to sleep for 0.5 seconds, you can use the `delay(500)` function. The loop() function keeps being executed again and again, so it's essential to include a delay in your code to control the timing of your program.

In addition to using the `delay()` function, you also need to set up the mode of the pin to OUTPUT with the pinMode() function. This ensures that your program can interact with external devices, such as LEDs and sensors.

A simple example of using the Arduino delay is to make an LED blink every 0.5 seconds. To achieve this, you can define a pin number for the LED and then use the `pinMode()` function to set it up as an output. You can also use the `digitalWrite()` function to turn the LED on and off.

Implementing Arduino delay in your code is essential if you want to control time. This means that you need to add some delay in your code to ensure that your program does not execute too quickly or slowly. For instance, if you're making an LED blink in your code, what will happen is that the LED will blink at a very high rate (multiple thousands times per second at least). To avoid this, you need to include a delay in your code.

An Arduino program works like this: first, the setup() function is executed once. Then, the loop() function is executed over and over again, until you power off your Arduino. Any program that you write will be executed at full speed unless you include delays in your code.

In summary, using Arduino delay with care is essential if you want to control time in your programs. You need to use delays to ensure that your program does not execute too quickly or slowly and to make sure that your external devices are properly controlled.
