Floating input pins

WebFloating pins are digital input pins that are not tied to a specific input voltage (either 0V or 5V) and thus, are subject to electromagnetic interference. Here, the button state is oscillating between HIGH and LOW simply due to the electromagnetic interference from my body. Makes me feel like Dumbledore! The source code is here. WebHi 🙂. So I keep reading everywhere that leaving a CMOS input pin floating is bad because it is high impedance, can oscillate, etc. I understand and agree. But while a MCU is starting up (or when you're programming it) all its pin are in input state until the program has started to set them as output or add an internal pull-up.
