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 ...

Figure an Arduino most matches the "Other" category. To be specific, it isn't an Arduino brand, it is a DigiSpark, but the trouble isn't with the device itself. The problem is with a buzzer. I got ...

Inside the cool laser-cut box is an Arduino Uno and a 9V battery, plus a current-limiting resistor and the all-important buzzer. ... to build a project based on your 1D LED pong, Arduino-style ...

The Arduino monitors the battery level and indicates its charge on the RGB status LED. The Arduino can also trigger the camera’s shutter using an NPN transistor and 2.5mm 3 pole jack.” ...
