Regardless if you are new to the world of electronics or will use the UNO as a tool for education purposes or industry-related tasks. First entry to electronics: If this is your first project within coding and electronics, get started with our most used and documented board; Arduino UNO. It is equipped with the well-known ATmega328P processor, 14 digital input/output pins, 6 analog inputs, USB connections, ICSP header and reset button. This board includes everything you will need for a great first experience with Arduino. Industry-standard development board: Using the Arduino UNO board in industries, there are a range of companies using the UNO board as the brain for their PLC’s. Education purposes: Although the UNO board has been with us for about ten years, it is still widely used for various education purposes and scientific projects. The board's high standard and top quality performance makes it a great resource to capture real time from sensors and to trigger complex laboratory equipment to mention a few examples.

A passive buzzer does not have a built-in oscillator, so it needs an AC audio signal to produce sound. ACTIVE BUZZERS Active buzzers are the simplest to use. They are typically available in voltages from 1.5V to 24V. All you need to do is apply a DC voltage to the pins and it will make a sound. Active buzzers have polarity. The polarity is the same as an LED and a capacitor – the longer pin goes to positive. One downside of active buzzers is that the frequency of the sound is fixed and cannot be adjusted. INSIDE AN ACTIVE BUZZER Let’s cut into an active buzzer to see what lurks beneath that neat plastic exterior: The gold disc on the right is a piezoelectric disk that vibrates when a voltage is applied. The three metal fingers on the PCB make contact with the disc, and a little transistor amplifier is on the printed circuit board. PASSIVE BUZZERS Passive buzzers need an AC signal to produce sound. the downside to this is that they will need more complex circuitry to control them, like an oscillating 555 timer or a programmable microcontroller like the Arduino. Passive buzzers have the advantage that they can vary the pitch or tone of the sound. Passive buzzers can be programmed to emit a wide range of frequencies or musical notes. INSIDE A PASSIVE BUZZER Now let’s cut open a passive buzzer: In a passive buzzer, we find an anatomy similar to a loudspeaker. There is a circular magnet surrounding an inner wire coil, with a disk that vibrates from the magnetic force generated by the electromagnetic coil. COMPONENTS - BUZZERS
