Servo data extract

[Reolan_Pillay]

I’m using an Arduino uno serially with Blynk, I wanted to know if anybody knows a method to gather a servo output reading and display on a gauge widget ?

This servo is already being controlled automatically, I just want to extract its movement NOT use a slider to determine its position.

Since your code MUST have some value it is sending to the servo control command, simply take that same value and also send it via Blynk.virtualWrite(vPin, value) to a properly configured Widget (set MIN MAX values in the widget to mimic that of the servo, typically 0-180 or sometimes I use 10-160).

In this example, along with a way of controlling a servo, I also use this exact method to set a gauge widget to simulate the same results…

#16 - Ultrasonic Distance Sensor with Servo This little project used the HC-SR04 Ultrasonic sensor… but instead of boring old distance numbers, it will also position a servo within a range of selected distances. This sketch demonstrates a timer that can be enabled and disabled, so as not to be running something like the Ultrasonic sensor if other critical timing functions need to run. And also demonstrates enabling and disabling the servo, so that there is no jitter or fluttering when it is n…
