//write a code in esp32 to control servo motor with the help of blynk console website there is slider in dashboard which is a virtual pin v0 for slider and when in the blynk dashboard the slider is slided to 50 or 60 then in wokwi the servo motor will be rotated to 50 and 60 degree simuntaneously and v1 is a virtual pin for gauge in blynk dashboard it will connected to ultrasonic to show the cm in wokwi
