So, I got a Raspberry Pi 4 Model B, and I'm trying to make a project using relay boards. Turns out, when I turn on my Pi, one of the pins is already active and the indicator turned on partially. I took a tester and kept on the GPIO pins just to find that they were active without any script activating them. Is my Pi defected or is it a built-in feature to keep the GPIOs on?
Please let me know. Thanks!
