Adafruit Wave Shield for Arduino Kit - v1.1

Adafruit Wave Shield for Arduino Kit - v1.1

Adding quality audio to an electronic project is surprisingly difficult. Here is a shield for Arduinos that solves this problem. It can play up to 22KHz 12bit uncompressed audio files of any length. It's low cost, available as an easy-to-make kit. It has an onboard DAC, filter and op-amp for high quality output. Audio files are read off of an SD/MMC card, which are available at nearly any store. Volume can be controlled with the onboard thumbwheel potentiometer. This shield is a kit, and comes with all parts you need to build it. Arduino, SD card, tools, speaker and headphones are not included. It is fairly easy to construct and anyone with a successful soldering project under their belt should be able to build it. The shield comes with an Arduino library for easy use; simply drag uncompressed wave files onto the SD card and plug it in. Then use the library to play audio when buttons are pressed, or when a sensor goes off, or when serial data is received, etc. Audio is played asynchronously as an interrupt, so the Arduino can perform tasks while the audio is playing. Can play any uncompressed 22KHz 16bit (on a 12bit DAC), mono Wave (.wav) files of any size. While it isnt CD quality, it is certainly good enough to play music, have spoken word, or audio effects. Check out the demo video/audio at the webpage Output is mono, into L and R channels, standard 3.5mm headphone jack and a connection for a speaker that is switched on when the headphones are unplugged Files are read off of a FAT16/FAT32-formatted SD/MMC card Included library and examples makes playing audio easy Please note that the library is rather bulky, requiring 10K of flash and more than 1/2 K of RAM for buffering audio. It works fine using any ATmega328-based Arduino (Duemilanove, Uno or compatible). This shield is not Mega or Leonardo compatible!

Adafruit Music Maker MP3 Shield for Arduino

Adafruit Music Maker MP3 Shield for Arduino

Bend all audio files to your will with the Adafruit Music Maker shield for Arduino! This powerful shield features the VS1053, an encoding/decoding (codec) chip that can decode a wide variety of audio formats such as MP3, AAC, Ogg Vorbis, WMA, MIDI, FLAC, WAV (PCM and ADPCM). It can also be used to record audio in both PCM (WAV). You can do all sorts of stuff with the audio as well such as adjusting bass, treble, and volume digitally. All this functionality is implemented in a light-weight SPI interface so that any Arduino can play audio from an SD card. There's also a special MIDI mode that you can boot the chip into that will read 'classic' 31250Kbaud MIDI data from an Arduino pin and act like a synth/drum machine - there are dozens of built-in drum and sample effects! But the chip is a pain to solder, and needs a lot of extras. That's why Adafruit spun up the best shield, perfect for use with any Arduino Uno, Leonardo or Mega. Here are some specs: Stereo audio out with proper audio filter caps and ground reference so it can be safely connected directly to headphones, a stereo system or other powered speakers 7 extra GPIO's that can be written or read through the Arduino Library for reading buttons or lighting LEDs MicroSD card socket, for any FAT16/FAT32 formatted SD card from 64Mb or greater. Full 3.3/5V level shifting for SD and MP3 chipsets Works with Arduino Uno, Mega, or Leonardo Built in MIDI synth/drum machine with dozens of instruments Plenty of optional breakouts for pins like the card-detect and microphone input Each order comes with one fully-assembled and tested shield, 2 2-pin terminal blocks, a stick of 0.1" male header and 2x3 female header for the ICSP connection. Some light soldering is required to attach the through-hole headers to the PCB for plugging into the Arduino as well as the terminal blocks for the speakers. Speakers, headphones, SD card and Arduino not included!

DFROBOT Gravity: Analog Capacitive Soil Moisture Sensor- Corrosion Resistant

DFROBOT Gravity: Analog Capacitive Soil Moisture Sensor- Corrosion Resistant

INTRODUCTION This product measures soil mositure levels by capacitive sensing, rather than resistive sensing like other types of moisture sensor. It is made of a corrosion resistant materal giving it a long service life. Insert it into soil and impress your friends with the real-time soil moisture data! The product includes an on-board voltage regulator which gives it an operating voltage range of 3.3 ~ 5.5V. It is compatible with low-voltage MCUs (both 3.3V and 5V logic). To make it compatible with a Raspberry Pi, an ADC converter is required. This sensor is compatible with our 3-pin "Gravity" interface, which means it can be directly connected to the Gravity I/O Expansion Shield. The following image shows an example project - a device that notifies you when a plant needs to be watered. APPLICATIONS Gardening & Farming Moisture Detection Intelligent Agriculture SPECIFICATION Operating Voltage: 3.3 ~ 5.5 VDC Output Voltage: 1.2 ~2.5 VDC Interface: PH2.0-3P SHIPPING LIST Capacitive Soil Moisture Sensor x1 Analog Sensor Cable x1
