This project involves using an LDR sensor and a button in a Blynk app to control a servo motor and an LED. The LDR sensor is used to detect the ambient light level and open or close the servo motor based on the sensor's reading. The button in the Blynk app is used to turn an LED on or off. This project demonstrates the ability to remotely control physical devices using a Blynk app and an ESP8266 microcontroller.

Make sure you use your own mobile hotspot, as university WIFI and public WIFI block the SSID connection.
The ssid is your mobile hotspot Network name and the pass is your mobile hotspot password.

4. Create a prototype as shown in figure below:
   
   
   
5. Once done, setup up the components:
   
   
   
6. Setup the Datastream for LEDs and LDR sensor respectively
   • V1 for LDR (change the MAX value to 300)
   • V2 for Green LED
   • V3 for White LED
   • V4 for Blue LED
   • V13 for RUN button
   • V14 for PAUSE button
   • V15 for STOP button
   • SuperChart to display the graph
7. Connect the circuit as shown in the diagram above

The other left behind legs are connected to the ground
