Wait
Note: The function wait is deprecated in favor of explicit sleep functions. To sleep, replace wait with ThisThread::sleep_for (C++) or thread_sleep_for (C). To wait (without sleeping), call wait_us. wait_us is safe to call from ISR context.
The wait_us and wait_ns functions provide precise wait capabilities. These functions spin the CPU to produce a small delay so they should only be used for short delays. Any delay larger than a millisecond will affect power and multithread performance, and block the platform deep sleep for the entire duration. Therefore, spinning for millisecond wait is not recommended, and ThisThread::sleep_for should be used instead.

Example
#include "mbed.h"
DigitalOut heartbeat(LED1);
int main() {
while (1) {
heartbeat = 1;
wait(0.5);
heartbeat = 0;
wait(0.5);
}
}
