Notification widgets are another subset of widgets that can be used to send notifications from your Raspberry Pi hardware. Some notification widgets can be integrated with third-party services such as Twitter and Blynk cloud. You can schedule your Raspberry Pi to send notifications to your smartphone (or tablet) or you can send them on a user action (if a button is pressed or depending on a threshold value).
