For microcontrollers without an analog-to-digital converter or when you want a higher-precision ADC, the ADS1015 provides 12-bit precision at 3300 samples/second over I2C. The chip can be configured as 4 single-ended input channels, or two differential channels. As a nice bonus, it even includes a programmable gain amplifier, up to x16, to help boost up smaller single/differential signals to the full range. We like this ADC because it can run from 2V to 5V power/logic, can measure a large range of signals and its super easy to use. It is a great general purpose 12 bit converter.
The chip's fairly small so it comes on a breakout board with ferrites to keep the AVDD and AGND quiet. Interfacing is done via I2C. The address can be changed to one of four options (see the datasheet table 5) so you can have up to 4 ADS1015's connected on a single 2-wire I2C bus for 16 single ended inputs.
To get you started, we have example code for both the Raspberry Pi (in our Adafruit Pi Python library) and Arduino (in our ADS1X15 Arduino library repository) Simply connect GND to ground, VDD to your logic power supply, and SCL/SDA to your microcontroller's I2C port and run the example code to start reading data.

Arduino GPS SD Accelerometer to log
The SD card, or Secure Digital card, is a non-volatile solid-state flash memory. Meaning if we disconnect power, it will retain its data. With an SD card we can expand Arduino's permanent storage by gigabytes. This is useful for applications that store large amounts of data such as data loggers. A 4GB SD card can be had for only $5.
POWERING THE SD CARD
The LC STUDIO SD card socket used in this project can be powered with 5V or 3.3V power sources. There is an LM1117 3.3V regulator on board which can handle 800mA of current. The Arduino can provide 3.3V directly but it's limited to 50mA. That's not enough to power the SD card. So I powered the SD card socket from the Arduino Uno's 5V pin which can handle over 500mA of current. The 5V pin on the SD card socket will pass through the LM1117 regulator and come out a 3.3V with a current ceiling of 800mAh.
Just because this SD card socket can be powered with 5V or 3.3V, we still can't connect 5V Arduino pins to the SD card socket's pins. We have to level-shift the Arduino's 5V signals to 3.3V before we can connect them to the SD card.
This is where the SN74AHC125 IC comes in handy. This IC can convert (level-shift) a total of 4 signals from 5V to 3.3V. This is perfect because for this project, I only need to convert 4 Arduino pins from 5V to 3.3V: three to the SD card socket and one to the LGS20031 GPS receiver which is also a 3.3V module.
ALTERNATIVES TO THE SN74AHC125
You can replace the SN74AHC125 with the more available CD4050. I recently bought 10 of those from Ebay for about $0.40 a piece. The CD4050 is not pin compatible with the SN74AHC125 but it's easy to use. You will find many useful wiring examples for the CD4050 on the web.
THE ARDUINO SD LIBRARY
The Arduino IDE comes bundled with an SD library that's easy to use. You can include the SD library in your Arduino program by selecting from the main menu: Sketch\Import Library\SD
The library also comes with ready to use example programs to get you up and running. You can open those example programs from main menu: File\Examples\SD then pick any of the 6 example sketches. If you have the SD card socket connected and an SD card inserted, those examples will work on the spot.
For this prototype, I am using an old XTREME MiniSD 1GB SD1 card with a standard SD adapter simply because I have one available. I did not run into any performance issues with this class and model. Most memory cards sold today are the faster SDHC variety.

ADXL345 3-Axis Digital Acceleration of Gravity Tilt Module for Arduino
Introduction
The ADXL345 is a small, thin, low power, 3-axis MEMS accelerometer with high resolution (13-bit) measurement at up to +/-16 g. Digital output data is formatted as 16-bit two’s complement and is accessible through either an SPI (3- or 4-wire) or I2C digital interface.
Features
- Supply Voltage: 2.0 - 3.6 VDC
- Ultra Low Power: As low as 23 uA in measurement mode, 0.1uA in standby mode at 2.5V
- SPI or I2C Communication
- Single Tap / Double Tap Detection
- Activity / Inactivity Sensing
- Free-Fall Detection
- The ADXL345 has special sensing abilities! The single and double tap sensing detects when a single, or two simultaneous, acceleration events occur. Activity and inactivity sensing detect the presence or lack of motion. Free-fall sensing compares the acceleration on all axes with the threshold value to know if the device is falling. All thresholds levels that trigger the activity, free-fall, and single tap/double tap events are user-set levels. These functions can also be mapped to one of two interrupt output pins. An integrated, patent pending 32-level first in, first out (FIFO) buffer can be used to store data to minimize host processor intervention.
- The ADXL345 is well suited to measure the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. Its high resolution (4 mg/LSB) enables measurement of inclination changes less than 1.0°. Furthermore, low power modes enable intelligent motion-based power management with threshold sensing and active acceleration measurement at extremely low power dissipation.

There are two different ways to record a voice message onto the chip viz. i) CN1 connector on PCB for external audio input or ii) Onboard Microphone. Jumper J3 on the PCB to select audio source. J3-Position A would select the external audio input and J3-Position M/P would select onboard microphone. Onboard preset PR1 will adjust the sampling rate of playback and record option for IC. Important thing to remember is that, if you increase the sampling rate, the duration of message will reduce and vice-versa. For details see resistance values & sampling frequencies table.
