RotaryEncoderDebounced
About the RotaryEncoderDebounced PCB
RotaryEncoderDebounced is an open source PCB design by XavierBerger, published on GitHub under the CERN-OHL-P-2.0 license. It is a 2-layer board measuring 23 × 20 mm, with 16 components from 8 distinct parts.
Other key parts include the 74HC14. By type, the board carries 6 resistors, 5 capacitors, 3 connectors, 1 IC and 1 switch.
From the project
Rotary Encoder with hardware Debouncer
A rotary encoder tracks shaft rotation by outputting pulses. However, mechanical switches in encoders suffer from contact bounce, causing false signals.
This projet propose a solution to debounced Rotary Encoder signal at hardware level.
When encoder contacts close or open, they bounce, creating multiple rapid signal changes. These can be misinterpreted as several rotations or direction changes.
