LM393 Sound Detection Sensor Module for Arduino detects whether sound has exceeded a threshold value. The sound is detected via microphone and fed into an LM393 op-amp.The sound level setpoint is adjusted via an onboard potentiometer. When the sound level exceeds the set point, an LED on the module is illuminated and the output is sent low.
Note: This sensor only recognizes the availability of sound cannot identify the size of the sound or the specific frequencies of sound.
Features:-Signal output indication.-The output is digital.-Single channel signal output.-With the retaining bolt hole, convenient installation.-Output low level and the signal light when there is sound.

If you want to add some visual output to your Arduino projects, you’ll need a display. If you need moderate data on display, the LCD2004 Parallel LCD Display is a quite good solution.This is LCD2004 Parallel LCD Display that provides a simple and cost-effective solution for adding a 20×4 Black on RGB Liquid Crystal Display into your project. The display is 20 character by 4 line display has a very clear and high contrast black text upon a yellow background/backlight.
This is great yellow backlight LCD display. It is fantastic for Arduino based project. This LCD2004 Parallel LCD Display with Yellow Backlight is very easy to interface with Arduino or Other Microcontrollers.
The values shown on the display can be either a simple text or numerical values read by the sensors, such as temperature or pressure, or even the number of cycles that the Arduino is performing.One thing to consider is you’ll waste about 8 Pins on your Arduino for the display to get working. Luckily there exists an I2C adapter that you can solder right onto the pins of the display. So all you need to connect are the I2C pins, which shows a good library and little of coding.For more displays click below,LED/LCD Display
Features:-20 characters wide, 4 rows-Black text on the yellow background-The module can easily interface with an MCU-The module is a low-power consumption character LCD Module with a built-in controller-Single LED backlight included can be dimmed easily with a resistor or PWM.-Can be fully controlled with only 6 digital lines! (Any analog/digital pins can be used)

"OLED’s are the destiny of shows, as they possess a number of the greatest blessings over both traditional show technology of LCD’s and LED‘s.
The maximum appealing factor about the use of the OLED shows is they do not want a back-mild like conventional LCD/LED displays. The organic cloth itself has a belongings known as Electroluminescence (EL), which reasons the cloth to “glow” whilst inspired by using a modern or an electric powered area. Best energy saving presentations ever!!!
This 0.91 inch 128×32 Blue OLED Display Module gives 128×32 pixel resolution. They are presenting an awful lot much less thickness than LCD shows with accurate brightness and also produce better and authentic colours. 
This OLED Display Module is very compact and will upload a exceptional ever consumer interface enjoy to your Arduino mission. The connection of this display with Arduino is made through the I2C(additionally referred to as as IIC) serial interface.
The 0.91 inch 128×32 Blue OLED Display Module produces blue textual content on black historical past with excellent comparison while supplied with DC 2.8V deliver. The OLED Display Modules additionally offers a very wide viewing perspective.
