•I2C-controlled• Works with both Raspberry Pi & Arduino• Low current draw (0.5m A when sensing, 15u A when idle)• Address select pins (up to 3 of these on a single I2C bus)• Separately measure infra-red, full-spectrum or human-visible light• Built in ADC means you can use this with any microcontroller (even if it doesn't have analog inputs)• Fully tested & assembled breakout board• All headers included (to solder yourself) The TSL2561 luminosity sensor is an advanced digital light sensor, ideal to be used in a wide range of light situations. Compared to low cost Cd S cells, this sensor is more precise, allowing for exact lux calculations & can be configured for different gain/timing ranges to detect light ranges from up to 0.1
- 40, 000+ Lux on the fly. The best part of this sensor is that it contains both infrared & full spectrum diodes! That means you can separately measure infrared, full-spectrum or human-visible light. Most sensors can only detect one or the other, which does not accurately represent what human eyes see (since we cannot perceive the IR light that is detected by most photo diodes) The sensor has a digital (i 2c) interface. You can select one of three addresses so you can have up to three sensors on one board
- each with a different i 2c address. The built in ADC means you can use this with any microcontroller, even if it doesn't have analogue inputs. The current draw is extremely low, so its great for low power data-logging systems. about 0.5m A when actively sensing, & less than 15 u A when in powerdown mode.

• The default 'max gain' is 60d B, but can be set to 40d B or 50d B by jumpering the Gain pin to VCC or ground• You can change the Attack/ Release ratio, from the default 1:4000 to 1:2000 or 1:500• The output from the amp is about 2 Vpp max on a 1.25V DC bias, so it can be easily used with any Analog/ Digital converter that is up to 3.3V input• If you want to pipe it into a Line Input, just use a 1u F blocking capacitor in series This fancy microphone amplifier module is a step above the rest, with built in automatic gain control. The AGC in the amplifier means that nearby 'loud' sounds will be quieted so they don't overwhelm & 'clip' the amplifier, & even quiet, far-away sounds will be amplified. This amplifier is great for when you want to record or detect audio in a setting where levels change & you don't want to have to tweak the amplifier gain all the time. The chip at the heart of this amp is the MAX9814 If you just need to keep track of audio levels, see this sound-level meter tutorial for Arduino found here Each order comes with one assembled & tested board, with an electret mic pre-soldered on, & a small piece of header. Adafruits tutorial will get you started with using & testing the microphone amplifier & you can check out their general-purpose microphone amplifier tutorial for other project ideas & code ...

• 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. ...

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. Simply download our library & connect the 3V/SCL/SDA/GND pins, install the library properly & upload our test program to read out accelerometer & magnetic field data. ...

- or for power-users we have instructions on how to modify an existing Arduino IDE install. The FLORA has USB (Universal Serial Bus) HID support, so it can act like a mouse or keyboard to attach directly to computers. FLORA has a small but easy to use onboard reset button to reboot the system. The power supply is designed to be flexible & easy to use. There is an onboard polarized 2 JST battery connector with protection schottky diode for use with external battery packs from 3.5 v to 16 v DC in. Can be used with Li Ion/ Li Poly, Li Fe, alkaline or rechargeable Ni Mh/ Ni Cad batteries of any size. The FLORA does not have a Li Po charger included by design, this allows safe use with multiple battery types & reduces risk of fire as it is not recommended to charge these batteries on fabric. We suggest one of our micro-lipo chargers if you want to use Li Po batteries with FLORA. FLORA has onboard power switch connected to 2 A power FET for safe & efficient battery on/off control. Often FETs are not included in wearable board designs which leads to switch failure as small SMT switches are rated for only 20 m A current use. The FLORA has an onboard 3.3 v 150 m A regulator with a protection diode & USB (Universal Serial Bus) fuse so that the microcontroller voltage is consistent & can power common 3.3 v modules & sensors. The FLORA power system is specifically designed to allow easy control & power of a large quantity of addressable Neo Pixels. Flora can easily drive 50 pixels directly from the onboard power supply, or up to 500 with the pixels externally powered by a separate 5 V supply. FLORA is fabric friendly-- all the components on board are flush to the PCB & won't snag delicate garments (it does not use FTDI headers). FLORA is extremely beginner-friendly
- it is difficult to destroy the FLORA by connecting a battery backwards due to polarized connector & protection diodes. The on-board regulator means that even connecting a 9 V battery will not result in damage or tears. The FLORA has 4 indicator LED's: power good, digital signal LED for bootloader feedback, data rx/tx. Also onboard is an ICSP connector for easy reprograming for advanced users. There are 14 sewing tap pads for attachment & electrical connections. Data buses are interleaved with power & ground pads for easy module & sensor attachments without worrying about overlapping traces which are not possible with conductive thread. The FLORA works with the Adafruit-fixed Leonardo-like bootloader & will work with any future released Leonardo-compatible bootloader. FLORA is currently using our bootloader & Adafruit USB (Universal Serial Bus) vendor ID.

• 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. ...
