Arduino pinMode(): When to use and why - Bald Engineer

Webb8 jan. 2010 · Hey Joerg, what's happening is that other Arduino boards support connecting an internal resistor to feed voltage into the pin, but fed through a high enough resistance that you can drag them low by shorting to ground (and not much current flows due to the high resistance). This gives a more reliable on/off indication as spurious momentary … Webb6 maj 2024 · This problem is caused by the high sensitivity of CMOS inputs - they will pick up stray fields and charge like you wouldn’t believe.
