hi, im new to blynk app and i need help with my project.

Im using arduino with esp8266 wifi module to connect to blynk server over wifi and i want to make a led widget on the app to turn on the led on press and dont switch it off until it reads the sensor data for an object infront of it. i require only the code needed for this specific function to build on it.

There are lots of coding example in the Sketch Builder. Have you looked at them?

They’ll obviously need some modification, but should get you started.
