Battery holder 2x CR2032 Switch

The piezoelectric buzzer has a simple structure in which a ceramic piezoelectric disk is affixed to a vibrating plate. An alternative voltage applied to this element will cause a contraction or diametrical expansion of the element. This feature is used to fold a vibrating plate, which generates sounds. 2x Passive Buzzer 5V features:

- Input voltage: 3V to 12V
- Diameter: 12mm
- Height: 7.5mm
- Pin spacing: 6.5mm
- Impedance: 16 Ohm
- Working frequency: 2 to 5 KHz
- Quantity: 1 unit

Level sensor for liquids with float.
The liquid level sensor acts as a switch. The state is changed by means of a magnet located on the float. It can be used to detect liquid levels that are too high or too low.
Ideal for all those applications where it is necessary to control the level of non-corrosive liquids such as water tanks, aquariums.

WS2812B are LEDs that have built-in logic, making it possible to vary the color of each LED individually.
WS2812B includes a integrated inside each LED, which allows each pixel to be accessed individually.
For this reason, these types of LEDs are called individually indexable.
They are based on the 5050 LED.
