- * App dashboard setup:
- *   Value Display widget on V5 with Frequency 1000
+ * This example shows how to send values to the Blynk App,  
+ * when there is a widget, attached to the Virtual Pin and it 
+ * is set to some frequencey
+ * 
+ * Project setup in the app:
+ *   Value Display widget attached to V5. Set any reading
