Electret Microphone Amplifier- MAX4466 with Adjustable Gain Maxim MAX4466 20-20KHz Electret Microphone Hover To Enlarge. Description: Add an ear to your ... moreproject with this well-designed electret microphone amplifier. This fully assembled and tested board comes with a 20-20KHz electret microphone soldered on. For the amplification. We use the Maxim MAX4466, an op-amp specifically designed for this delicate task! The amplifier has excellent power supply noise rejection, so this amplifier sounds really good and isn't nearly as noisy or scratchy as other mic amp breakouts we've tried! This breakout is best used for projects such as voice changers. Audio recording/sampling, and audio-reactive projects that use FFT. On the back, we include a small trimmer pot to adjust the gain. You can set the gain from 25x to 125x. That's down to be about 200mVpp(for normal speaking volume about 6" away) which is good for attaching to something that expects'line level' input without clipping, or up to about 1Vpp, ideal for reading from a microcontroller ADC. The output is rail-to-rail so if the sounds gets loud, the output can go up to 5Vpp! Using it is simple: connect GND to ground. VCC to 2.4-5VDC. For the best performance, use the"quietest" supply available(on an Arduino, this would be the 3.3V supply) The audio waveform will come out of the OUT pin. The output will have a DC bias of VCC/2 so when its perfectly quiet, the voltage will be a steady VCC/2 volts(it is DC coupled) If the audio equipment you're using requires AC coupled audio, place a 100uF capacitor between the output pin and the input of your device. If you're connecting to an audio amplifier that has differential inputs or includes decoupling capacitors, the 100uF cap is not required. The output pin is not designed to drive speakers or anything but the smallest in-ear headphones- you'll need an audio amplifier if you want to connect the amp directly to speakers. If you're connecting to a microcontroller pin. You don&#

High auxiliary rod resistance and fault connections AC powered with rechargeable NiMH batteries Rugged. Dustproof and rainproof field case Can also be used for continuity tests on bonding Color-coded terminals Applications Three-Point measurements of resistance to ground of ground rods and grids. Three-point measurements are generally used when the electrode or grid can be easily disconnected. If corrosion is suspected, or in circumstances where ground faults are unlikely to occur Four-Point tests or soil resistivity measurements. Locating areas of lowest soil resistivity is essential for achieving an economical grounding installation Touch potential measurements. An alternative to 3-Point tests in evaluating electrical safety. This test is recommended when the ground cannot be disconnected, where ground faults are highly likely to occur, or when the"footprint" of grounded equipment is comparable to the size of the ground to be tested.

Description The WTV020SD is a small. Simple IC for embedding audio-playback into your next project. These devices are commonly used in children’s toys ... moreand“talking” retail displays. This breakout board allows you to access the functionality of the WTV020SD to give a voice to your next project. The breakout board includes a battery connector and a micro-SD card slot. Simply load your audio files onto a micro-SD card and plug it in. Power up the module and trigger the playback. Playback can be triggered in either key or serial mode: The key-mode provides a stand alone operation where a host micro is not required. With only 3 push buttons. A 3V battery and a speaker, an extremely compact and low component count MP3-Player like system can be implemented. The serial-mode provides a simple. 2-wire interface to any micro-controller via its DATA and CLK lines. Audio operations such as PLAY, PAUSE, STOP and VOLUME control functions are all available to the host micro via simple serial commands. The audio compression used in this module is a little strange(4-bit ADPCM@ 6-32kHz) so you’ll need to download the utility in the documents below in order to convert your.WAV files into the 4-bit ADPCM format required. Features: Low-cost module for all embedded Audio-Sound applications. Supports 4-bit ADPCM(ad4) file formats with sampling rates from 6Khz to 36Khz. Two operation modes: Serial Mode: Supports a 2-Wire(Data. Clock) interface to any micro-controller. Key Mode: Supports a simple stand alone operation without a host micro. Differential 2 line PWM output for direct speaker connection(8 Ohm/0.5W) Dedicated 16-bit DAC/PWM audio output to use with an external amplifier. On-board micro-SD memory card adaptor for storing of audio. Voice and music files(up to 512 files) Supports 64Mb to 2Gig micro-SD memory cards(FAT format) Low Power Idle current of 8.0uA, RoHS Compliant, Documents: WTV020SD) Package Included: 1 x WTV020SD Module Shipping Terms, 1.

Description: This is the new version Uno R3. In addition to all the features of the previous board. This allows for faster transfer rates and more memory. ... moreNo drivers needed for Linux or Mac(inf file for Windows is needed and included in the Arduino IDE) and the ability to have the Uno show up as a keyboard, mouse, joystick, etc. The Uno R3 also adds SDA and SCL pins next to the AREF. In addition. There are two new pins placed near the RESET pin. One is the IOREF that allow the shields to adapt to the voltage provided from the board. The other is a not connected and is reserved for future purposes. The Uno R3 works with all existing shields but can adapt to new shields which use these additional pins. Arduino is an open-source physical computing platform based on a simple i/o board and a development environment that implements the/ language. Arduino can be used to develop stand-alone interactive objects or can be connected to software on your computer(e.g. Flash. Processing, MaxMSP) The open-source IDE can be downloaded for free(currently for Mac OS X, Windows, and Linux) Note: The Uno R3 requires the Arduino 1.0 drivers folder in order to install properly on some computers. We have tested and confirmed that the R3 can be programmed in older versions of the IDE. However. The first time using the R3 on a new computer, you will need to have Arduino 1.0 installed on that machine. If you are interested in reading more about the changes to the IDE, check out the official! Features: ATmega328 microcontroller, Input voltage- 7-12V, 14 Digital I/O Pins(6 PWM outputs) 6 Analog Inputs, 32k Flash Memory, 16Mhz Clock Speed, Replace the USB interface into micro interface, can easily download mobile by phone charging cable. Total compatible with win7&win8. shipping PAYMENT TERMS: 1.we only accept payment view paypal.
