ESP8266 Digital input not constant floating from 0 to 1

[Cleric182]

Hello all,
i am facing an issue on setting a int based on a digital input(D5).When the DI is High (conected to the 3.3v) the values are always swapping between 0 and 1. When Connected directly to the ground the value is stable at 0 as expected.

thank you

Your high source of power probably has high impedance. Can you try use pulldown resistor? What is your circuit?

Have you tried isolating the power source rather than powering it off of the 3.3v esp8266 board Also hello world. 8 year lurker, multiple accounts and our first comment. https://photos.app.goo.gl/nNvBtRecbf1XrYjH6
