Story

As our day to day life schedule is busy we hardly get time to do minor task or even forgot completely and because of this further we have to face some problem.

One of the problem is our laptop battery monitoring, as we know that our laptop battery are built to handle a certain number of charge cycle and after the cycle's are over we experience discharge of battery very fast. Today's technology is so advance that we have build in feature of battery draining notification but as per our busy schedule sometimes we ignore the notification or also forgot to take action on it. Kindoff sometimes we suffer and find our loss.

Keeping this in mind with the help of BOLT IOT kit I have created a project which monitors the laptop battery and at particular or recommended percent generate alert with the help of Buzzer. Also at same time we also monitor the Laptop CPU utilization. As High utilizatiion affect the performance of system, we have alert system as CPU utilization goes beyond the recommended percent, with help of BOLT IOT LED will glow till the utilization get below the range.

    response = buzzer.digitalWrite(pin, value)
    
while True:

 print ("CPU usage is", cpu_alert)

 if alert_battery >= int(percent):
     if plugged==False:

 Battery = battery.percent
 if Battery == 100:
