GY-4466 Professional MAX4466 High Precision Electret Microphone Amplifier with Adjustable Gain for Arduino ()- Features:
Add an ear to your project 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!

It's a low tech sensor, but ideal for monitoring an urban garden, or your pet plant's water level. This is a must have tool for a connected garden!
This sensor uses the two probes to pass current through the soil, and then it reads that resistance to get the moisture level. More water makes the soil conduct electricity more easily (less resistance), while dry soil conducts electricity poorly (more resistance).
It will be helpful to remind you to water your indoor plants or to monitor the soil moisture in your garden.

New Led Ring 16x 5050 RGB LED Board with Integrated Drivers Module Geekcreit for Arduino - products that work with official Arduino boards ()16 ultra bright smart LED are arranged in a circle with 1.75" (44.5mm) outer diameter.The rings are 'chainable' - connect the output pin of one to the input pin of another. Use only one microcontroller pin to control as many as you can chain together!Each LED is addressable as the driver chip is inside the LED.Each one has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim.Power the whole thing with 5VDC (4-7V works) and you're ready to rock.There is a single data line with a very timing-specific protocol.Since the protocol is very sensitive to timing, it requires a real-time microconroller such as an AVR, , PIC, mbed, etc.It cannot be used with a Linux-based microcomputer or interpreted microcontroller such as the netduino or Basic Stamp.As it requires hand-tuned assembly it is only for AVR cores but others may have ported this chip driver code so please google around.An 8MHz or faster processor is required.Comes as a single ring with 16 individually addressable RGB LEDs assembled and tested.Add to Cart7.14€ -

- VIN. The input voltage to the Arduino board when it's using an external power source (as opposed to 5 volts from the USB connection or other regulated power source). You can supply voltage through this pin, or, if supplying voltage via the power jack, access it through this pin.
- 5V.This pin outputs a regulated 5V from the regulator on the board. The board can be supplied with power either from the DC power jack (7 - 12V), the USB connector (5V), or the VIN pin of the board (7-12V). Supplying voltage via the 5V or 3.3V pins bypasses the regulator, and can damage your board. We don't advise it.
- 3V3. A 3.3 volt supply generated by the on-board regulator. Maximum current draw is 50 mA.
- GND. Ground pins.
- IOREF. This pin on the Arduino board provides the voltage reference with which the microcontroller operates. A properly configured shield can read the IOREF pin voltage and select the appropriate power source or enable voltage translators on the outputs for working with the 5V or 3.3V.
