Hee Haw Sound

This experiment creates a Hee Haw sound for an alarm. The diagram shows the number of cycles for the HEE and the time taken for each cycle, equates to a certain length of time. The frequency of the HAW is lower and the number of cycles must be worked out so that the time for the HAW is equal to the time for the HEE. This is simple when writing the program. The values loaded into the two files for the HEE are reversed for the HAW. The routine consists of two sections: HEE and HAW. Each section has two nested loops. The inner loop creates the length of time for the HIGH and LOW to produce a single cycle and the outer loop creates the number of cycles.
