This example shows how to use the SpeakUp Click board with a multimeter acting as a display to show the results of the voice commands.

There is an accompanying 10.5 minute long step-by-step video tutorial that shows how to create this project from the beginning: SpeakUp Multimeter Video Tutorial

Step 6. Connect your digital multimeter probes to the SpeakUp click board using a set of test clips. The multimeter should be used in DC Volts mode. The red lead on your meter connects to the IO 1 pin, and the black lead on your meter connects to the GND ground pin.

Connecting the test leads

Step 7. Power the SpeakUp click using an external USB wall power supply and let it check the room for ambient noise for the first 10 seconds.

Step 8. You are now ready to try out the voice recognition module.

Port On When you say "Port On" the multimeter should read 3 volts. This sets the IO 1 pin to on.

Port Off When you say "Port Off" the multimeter should read 0 volts. This sets the IO 1 pin to off.

Half-Duty When you say "Half Duty" the multimeter should read approximately 1.5 volts. This mode is created with the SpeakUp Utility's Pulse action set to a 50% duty ratio.
