Output Devices

Output devices are components of a computer system that are responsible for displaying or presenting processed data or information to the user. These devices take digital data from the computer and convert it into a human-readable form, typically through visual, audio, or tactile means. Common output devices include: Monitors: These display screens show visual output in the form of text, graphics, images, and videos. Printers: Printers produce hard copies of digital documents or images on paper or other physical media. Speakers: Audio output devices produce sound, including music, speech, or other auditory information. Projectors: Projectors display visual output on a larger screen or surface, typically for presentations or entertainment purposes. Plotters: These devices are used for producing high-quality, large-format graphics, such as architectural drawings or engineering designs. Braille Embossers: These devices translate digital text into Braille characters for visually impaired users. Output devices play a crucial role in allowing users to interact with and interpret the information processed by computers, enabling communication and understanding between humans and machines.

1. Idea & design

This week I worked with the buzzer since it seems to me that it is a basic signal and not so complex to manage with the RP2040. This week I will use the design made in kicad.

Description of buzzer TMB12A05

A buzzerr is a device that is capable of sending warnings through sound. It can be mechanical, electromechanical or piezoelectric. Typical buzzers are piezoelectric, these elements suffer a phenomenon known as piezoelectricity that occurs in certain crystals. It consists of certain materials, when subjected to mechanical stress, producing a potential difference. This also happens the other way around, when subjected to an electric field, they deform. Therefore, if an electrical signal is applied to the material, it deforms and when deformed it produces a sound. This is the base of the buzzer. If a voltage that varies over time can be supplied from an Arduino pin, different sounds can be reproduced. The TMB12A05 is an active buzzer that acts as an alarm or acoustic signal when a voltage of 3V is supplied.
