Pro Mini ATMEGA328P 5V/16MHz for arduino (Pro Mini ATMEGA328P)
It's blue! It's thin! It's the Arduino Pro Mini! SparkFun's minimal design approach to Arduino. This is a 5V Arduino running the 16MHz bootloader. Arduino Pro Mini does not come with connectors populated so that you can solder in any connector or wire with any orientation you need. We recommend first time Arduino users start with the Uno R3. It's a great board that will get you up and running quickly. The Arduino Pro series is meant for users that understand the limitations of system voltage (5V), lack of connectors, and USB off board.

We really wanted to minimize the cost of an Arduino. In order to accomplish this we used all SMD components, made it two layer, etc. This board connects directly to the FTDI Basic Breakout board and supports auto-reset. The Arduino Pro Mini also works with the FTDI cable but the FTDI cable does not bring out the DTR pin so the auto-reset feature will not work. There is a voltage regulator on board so it can accept voltage up to 12VDC. If you're supplying unregulated power to the board, be sure to connect to the “RAW” pin and not VCC.

LilyPad Coin Cell CR2032 Battery Holder (switch wearable CR2032 holder)
Sure, your flashing, chip-tune playing t-shirt is really cool at the party... but at some point you need to turn it off. And yes, you could just pull the battery, or maybe you've even sewn a LilyPad slide switch in-line. Wouldn't it be nice if there was just a switch on the battery? Well look no further.

This LilyPad Coin Cell Battery Holder has a small slide switch installed on the board, in-line with the power so you can shut off your project and save batteries. This slide switch is the same as is found on the LilyPad slide switch board, so it's not easy to accidentally turn off or on.

Just like the original Coin Cell Battery Holder, this simple board holds a 20mm coin cell battery (such as a CR2032) and gives you 4 connection points (two positive and two negative) for sewing into your project.

LilyPad Buzzer module (wearable buzzer)

This is a small buzzer for the LilyPad system. Use 2 I/O pins on the LilyPad main board and create different noises based on the different frequency of I/O toggling. Loud enough to hear inside a pocket but not obtrusively loud.

Please note: This is an inductive buzzer meaning that is will act as a short to ground if you are not actively driving it. We recommend you put both I/O pins to low (0V) when the buzzer is not used. Also, it's come to our attention that washing these buzzers will damage them. Until we've figured out a solution to this, avoid washing any portion of your project that contains one of these buzzers.

Interface



VCC: power positive
DOUT: TLL high/low level signal output
GND: power negative
AOUT: sampling current signal conversion voltage output port

Analog voltage signal output (AOUT)

Relationship between detection current and analog signal output is shown below:

Analog signal output: V0=Vcc*0.5±la*K (la is actual current through current detection pin, and K is linearity)

Eg: Input current is 1A, Vcc=5V and WS1800 linearity is 60mV/A
  1. When the current flows in from positive direction: V0=Vcc*0.5+la*K, V0=(2.5+0.06)V=2.56V
  2. When the current flows in from negative direction: V0=Vcc*0.5-la*K, V0=(2.5-0.06)V=2.44V
  3. If it is an AC signal: V0=Vcc*0.5+la*K, V0=(2.5+0.06)V=2.56V

The above are ideal values. There might be some precision errors.

On/Off output(DOUT)

  1. Make sure the current flows in from the positive direction. Adjust to the desired current warning level.
  2. LED will be on when current is below the setting and DOUT will be low.
  3. When the detected current is higher than your setting, the LED will turn off and the DOUT pin will go high.

This includes all of the current Arduino modules!
 
The AS3935 Franklin Lightning Detector gives you lightning detection for your next weather project. This sensor is capable of detecting lightning up to 40 km away with an accuracy of 1km to the storm front! On the product is a sensitive antenna tuned to pick up lightning events in the 500kHz band. When sensing an event the AS3935 utilizes an interrupt to the interrupt pin, distinguishes between false and real lightning events, and has a number of features to help calibrate lightning detection. For example, there are settings for detecting from indoors or detecting from outdoors, settings to change the threshold for false events, and settings to be alerted only after a certain number of lightning strikes to name a few. We've also written an Arduino Library to get you prepared for that upcoming storm!
