switch signal debounce circuit
Budget: €8 – €30 EUR
I need a switch signal debounce and timing circuit for a mechanical switch and operates on a low voltage range of 0-3.3V.
Switch is taking a pulled-up GPIO on a MCU on one pin and GND on the other. Circuit would be simple passive elements, and take as little power as possible from the pullup (2-4ma max in peak) . When the mechanical switch closes, the circuit should turn the pullup pin to be grounded for 100 to 200ms.
The button is not expected to be actuated more than one time every 5 seconds, so it is ok if the circuit is slowly charging for half second after an actuation.
Skills and experience required:
- Expertise in circuit design and analysis
- Knowledge of debounce circuitry and techniques
- Proficiency in programming microcontrollers
- Familiarity with low voltage circuitry and components
