• Fully tested & assembled breakout board• All headers included (to solder yourself)• Great low-noise performance•20-20 K Hz electret microphone• Maxim MX4466 op-amp for amplification• Small trimmer pot on the back to adjust gain (25x to 125x) Add an ear to your project with this well-designed electret microphone amplifier. This fully assembled & tested board comes with a 20-20 K Hz 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 & 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, & 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 200m Vpp (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 1 Vpp, 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 5 Vpp! 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). Connect the OUT pin directly to the microcontroller ADC pin. ...

It's an easy way to get started & an advanced tool for professionals. It's a collection of simple parts that work well together. Fadecandy is designed to enable art that is subtle, interactive, & playful
- exploring the interplay between light, form, & shadow. If you’re tired of seeing project after project with frenetic blinky rainbow fades, you’ll appreciate how easy it is to create expressive lighting! It's also battle tested! The firmware was originally developed to run the Ardent Mobile Cloud Platform, a Burning Man project which used 2500 LEDs to project ever-changing rolling cloud patterns onto the interior of a translucent plastic sculpture. It used five Fadecandy boards, a single Raspberry Pi, & the effects were written in a mixture of C & Python. The lighting on this project blew people away, & it made me realize just how much potential there is for creative lighting, but it takes significant technical drudgery to get beyond frenetic-rainbow-fade into territory where the lighting can really add to an art piece instead of distracting from it.

• Classic 3-axis accelerometer can tell which direction is down by measuring gravity or how fast the board is accelerating in 3D space• Magnetometer can sense where the strongest magnetic force is coming from (generally magnetic north)•I2C interface• Attaching it to the FLORA is simple: line up the sensor so its adjacent to the SDA/SCL pins & sew conductive thread from the 3V, SDA, SCL & GND pins. They line up perfectly so you will not have any crossed lines. Add motion & direction sensing to your wearable FLORA project with this high precision 3-axis Accelerometer+ Compass sensor. Inside are two sensors, one is a classic 3-axis accelerometer, which can tell you which direction is down towards the Earth (by measuring gravity) or how fast the board is accelerating in 3D space. The other is a magnetometer that can sense where the strongest magnetic force is coming from, generally used to detect magnetic north. By combining this data you can then orient yourself. We based this sensor on the latest version of this popular sensor, the LSM303DLHC. The sensor has a digital (I2C) interface. Attaching it to the FLORA is simple: line up the sensor so its adjacent to the SDA/SCL pins & sew conductive thread from the 3V, SDA, SCL & GND pins. They line up perfectly so you will not have any crossed lines. You can only connect one of these sensors to your FLORA, but you can connect other I2C sensors/outputs by using the set of SCL/SDA pins on the opposite side. Get started with the FLORA Accelerometer click here for the guide! It uses the same Arduino library as our conventional form LSM303 breakout. The example & library code will work 'out of the box' with FLORA.

• Output voltage increases with light on the sensor• Logarithmic response not only gives more sensitivity in low light, its also almost impossible to ""max-out"" the sensor• Dynamic range of 3 to 55, 000 Lux• Use indoors & outdoors without needing to recalibrate! Upgrade a project that uses a photocell with the GA1A12S202 analogue light sensor. Like a Cd S photo-cell, the sensor does not require a microcontroller, the analog voltage output increases with the amount of light shining on the sensor face. This sensor has a lot of improvements that make it better for nearly any project. The biggest improvement over plain photocells is a true log-lin relationship with light levels. Most light sensors have a linear relationship with light levels, which means that they're not very sensitive to changes in darkened areas & 'max' out very easily when there's a lot of light. Sometimes you can tweak a resistor to make them better in dark or bright light but its hard to get good performance at both ends. This sensor is logarithmic over a large dynamic range of 3 to 55, 000 Lux, so it has a lot of sensitivity at low light levels but is also nearly impossible to ""max out"" so you can use it indoors or outdoors without changing code or calibration. Since the sensor is fabricated on a chip, there are also fewer manufacturing variations, so you won't have to calibrate the sensor from one board to another. Using the sensor is easy as pie: connect the Vin to 2.3-6VDC, Gnd to ground & measure the analogue output on OUT. It will range up to 3V (at extremely bright outdoor sunlight). On an Arduino, just use analog Read () with the OUT pin connected to an analogue pin. For more information including graphs, power consumption, etc check out the datasheet On this breakout there’s a 68KO resistor from OUT to ground to turn the current into a voltage. ...

The Attiny 85 is a fun processor because despite being so small, it has 8K of flash, & 5 I/O pins, including analog inputs & PWM 'analog' outputs. Adafruit have designed a USB (Universal Serial Bus) bootloader so you can plug it into any computer & reprogram it over a USB (Universal Serial Bus) port just like an Arduino (it uses 2 of the 5 I/O pins, leaving you with 3). In fact they even made some simple modifications to the Arduino IDE so that it works like a mini-Flora. Even though you can program GEMMA using the Arduino IDE, it's not a fully 100% Arduino-compatible. There are some things you trade off for such a small & low cost microcontroller!•GEMMA does not have a Serial port connection for debugging so the serial port monitor will not be able to send/receive data• Some computers' USB (Universal Serial Bus) v 3 ports don't recognize the GEMMAs bootloader.

These pixels have full 24-bit color ability with PWM taken care of by the controller chip. Since the LED is so bright, you need less current/power to get the effects you want. The driver
is constant current so its OK if your battery power changes or fluctuates a little. Each pixel draws as much as 60mA (all three RGB LEDs on for full brightness white). In theory, the Flora can drive up to 500 pixels at 30 FPS (it will run out of RAM after that). However, after about 10 pixels (or if the distance between pixels is more than an inch or two) the resistance of the thread can affect the power supply. For large quantities of pixels over 10, you may want to consider using stranded core wire or copper braid to provide a "power bus" for the pixels - the current draw will add up fast!
