An application of using a microphone with an arduino is if you want to build some type of sound alarm circuit, in which sound triggers a circuit event such as flashing sirens or turning on a buzzer. For example, if you have a room that should be very quiet and someone breaks into it,...
The UART or serial module that is attached to the back of the LCD is responsible for sending and receiving serial communications between the Arduino and the LCD and it has a onboard potentiometer to adjust the brightness of the screen. What you need for this project is: An Arduino UNO Seri...
