In this section, Ozzy gets a voice.

This required adding a speaker and speaker power (five volts) according to the schematic below.

This required a connection from pin 32 of the Arduino Mega to pin 4 of the voice control module.

"Ozzyvoice0424" was modified to accept voice output statements, while "homely master0424" was modified to send the "detected human target" information to the voice module.
