This MP3 shield board is designed based on VS1053B from VLSI. using this shiled you can plug in your arduino UNO/MEGA direcly as showing in pic, dont' need need to hook up with jumpers, it's becomes more easy to play music compared with the tiny mp3 breakout board. VS1053 is a versatile MP3 codec processor that is capable of decoding a variety of music formats,including Ogg Vorbis/MP3/AAC/WMA/MIDI audio. For the best headphone listening experience, the VS1053 includes EarSpeaker spatial processing which accurately simulates how a room with stereo loudspeakers would sound. In addition to being able to decode all major formats, VS1053 is capable of recording in Ogg Vobis file.

Description: Piezo elements come in handy when you need to detect vibration or a knock. You can use these for tap or knock sensors pretty easily by reading the voltage on the output. They can also be used for a very small audio transducer such as a buzzer.
Description: This basic piezo sensor from Measurement Specialties is often used for flex, touch, vibration and shock measurements. A small AC and large voltage (up to +/-90V) is created when the film moves back and forth. A simple resistor should get the voltage down to ADC levels. Can also be used for impact sensing or a flexible switch.

Description: The Minisense 100 from Measurement Specialties is a low-cost cantilever-type vibration sensor loaded by a mass to offer high sensitivity at low frequencies. Useful for detecting vibration and ‘tap’ inputs from a user. A small AC and large voltage (up to +/-90V) is created when the film moves back an forth. A simple resistor should get the voltage down to ADC levels. Can also be used for impact sensing or a flexible switch.

Description
Non-invasive AC current sensor (10A max)
Used for measuring alternating current
Ferrite core material
The SeeedStudio Non-Invasive AC Current Sensor (10A Max) are sensors that are used for measuring alternating current. They are particularly useful for measuring whole building electricity consumption (or generation for that matter). The split core type is particularly suitable for DIY use it can be clipped straight on to either the live or neutral wire coming into the building without having to do any high voltage electrical work

Description: These are very thin variable potentiometers. By pressing down on various parts of the strip, the resistance linearly changes from 100Ohms to 10,000Ohms allowing the user to very accurately calculate the relative position on the strip. Can be used as an accurate positional indicator for CNC head positioning, variable user input (volume level input for example), straight user input (multiple button areas translate to given resistance levels), and many other applications.

Description: Basic breakout board for the TEMT6000 Ambient Light Sensor. Only what you need, nothing you don’t. Sensor acts like a transistor - the greater the incoming light, the higher the analog voltage on the signal pin.
Description: This AT407 basic tilt switch can easily be used to detect orientation. Inside the can is a ball that make contact with the pins when the case is upright. Tilt the case over and the balls don’t touch, thus not making a connection.
