it is the first time i am tinkering with ds18b20 temperature sensor. i wired it like this: https://www.tweaking4all.com/wp-content/uploads/2014/03/ds18b20-arduino-connected.jpg
but to my surprise as soon as i start arduino with sensor connected it immediately disconnects, power led flickers as if there was a problem with power. right after sensor disconnection, arduino continues function.
anyone can please hint me what could be the problem? i expected this to be rather a simple task.
