Why to apply debounce circuits?

Mechanical switches and buttons often generate noisy signals when pressed or released. This tool helps you design a debounce circuit (RC filter) or select a software delay to stabilize your digital inputs. Enter your desired debounce time and get resistor-capacitor recommendations or software timing hints.

The formula is:

\[ debounce_{time} = 5 \times R \times C \]
