What is the latency of Arduino Delay 200?

It's not that the arduino wants to delay, but that you need to wait for a certain amount of time to communicate with a device in your application or to execute commands such as sensors, effectors, etc., which is actually linked to reality, just imagine if the motor rotates 100 times without delay, 10,000 turns without delay, the hydraulic cylinder has no movement process, and directly reaches the designated displacement point instantaneously, then there is no concept of time in life, so whether the delay is not determined by the arduino, It's up to the application.

delay(200) is approximately equal to 200 milliseconds = seconds.

The precision of the delay function is actually not high).

delay (time) is a delay function that is time-in-milliseconds.

delaymicroseconds (time) is a delay function, time in microseconds.

delay, such as calculating time, etc.

It's just a function of doing nothing at this time.

Because each operation consumes a certain amount of time, although some times are short, they cannot be operated continuously, so a certain delay is sometimes required.

The question is not comprehensive, one, the program itself is simple, to cancel this delay directly do not run this sentence, method, delay(1000000), this sentence does not run. Bright 1000s is too long, just change it to a delay.

Second, it can be turned into a conditional statement, which is ...... with ifAnd then high

Third, the program in the loop is infinitely looped, and it can be executed once with while

put delay(1000000); It's good to remove it.

Or change it to a shorter time, say 1 second.

delay(1000);

Delay is not applicable

Because during the delay period, all chip resources are occupied.

It can be replaced by while.

In the Arduino program.

delay(1) indicates a delay of 1 millisecond.

delaymicroseconds(1) refers to the delay of 1 microseconds, and in fact, due to the limitation of the performance of the hardware itself, the delay of 1 microsecond may be biased, if the parameter is within 16383, the error will be within 3 us, but if the parameter is too large, it may be more error!

Literally, the time unit of delay50ms() is 50ms, and the time unit of delay50ms(20) is not known, and it depends on the function body.

Go check this out.

I used the millis() function in Arduino, which is a function that constantly updates the time value.

By taking different recording points, you can get the time difference between different recording points. It's very convenient.

But this function simply doesn't stop, haha.

10 in if(atime > 10) is the time, = the program is executed every 10ms, 1 second = 1000ms 10ms = 100 times seconds (number of executions) If you want to execute faster or slower, you can modify this number, this time value is just a myopia value, excluding your program execution time, if the program is not very complicated, basic or slightly other time.

This is related to the clock frequency of the chip of the Arduino board you use, so I recommend you to use the following method. As much delay as possible, there is as much time as possible, hehe.

void loop:

With the millis() function, you can refer to the following.

delay is the delay, and the semicolon is used at the end after filling in the number in parentheses.

The precise timer is used, the inaccurate software delay is used, and the assembly language delay (also known as the software delay) can be used in between

Use a timer
