Question: A student uses the code below in a continuous loop to generate a 200 Hz square wave, noting the period of 200 Hz is 5

A student uses the code below in a continuous loop to generate a 200 Hz square wave, noting the period of 200 Hz is 5 ms.

redled = 1; wait_ms (2.5); redled = 0; wait_ms(2.5); // flash red

He is then surprised to measure a frequency of 250 Hz. Explain why this is so.

redled = 1; wait_ms (2.5); redled = 0; wait_ms(2.5); // flash red led
