This is not necessary here because the tilt sensor module have a built-in (1ms) “hardware debounce” arrangement using a simple RC network (R-10K & C-100n). Sketch: Analog. This example code lights up ...

Here is a tested Arduino project that uses 3 sensor probes as water level indicator with 3 leds and one LCD display + a simple controller that turns on a motor when the water has reached the desired ...

This Arduino-based Pomodoro timer project also uses this 25-minute cycle. Once you push the button to start the timer, ... you can just build it a custom sensor with an Arduino Uno.
