Automatic battery level check in C#

Automatic battery level check in C#

I'm working on a speech recognition program in C# and I've compiled a few
lines of code that speaks back the current battery level when I say
"battery level".
if (e.Result.Text.ToLower() == "battery level")
{
System.Management.ManagementClass wmi = new
System.Management.ManagementClass("Win32_Battery");
var allBatteries = wmi.GetInstances();
//String estimatedChargeRemaining = String.Empty;
int batteryLevel = 0;
foreach (var battery in allBatteries)
{
batteryLevel = Convert.ToInt32(battery["EstimatedChargeRemaining"]);
}
if(batteryLevel < 25)
JARVIS.Speak("Warning, Battery level has dropped below 25%");
else //Guessing you want else
JARVIS.Speak("The battery level is at: " + batteryLevel.ToString() + "%");
return;
}
Instead of this line happening only when I say "battery level" I want it
to automatically check the battery level every 15mins and automatically
report back to me via speech if the battery level has dropped bellow 25%:
if(batteryLevel < 25)
JARVIS.Speak("Warning, Battery level has dropped below 25%");
I am guessing I will require a timer but other than that I have no idea.
Thanks.
