Adafruit ADXL345 - Triple-Axis Accelerometer I2C/SPI ShieldFilling out our accelerometer offerings, we now have the really lovely digital ADXL345 from Analog Devices, a triple axis accelerometer with digital I2C and SPI interface breakout. We added an on board 3. 3V regulator and logic level shifting circuitry, making it a perfect choice for interfacing with any 3V or 5V microcontroller such as the Arduino. The sensor has three axes of measurements, X Y Z, and pins that can be used either as I2C or SPI
Its smaller and lighter than a large optical microscope but packs quite a bit of power in its little body
simply plug in an FTDI cable and use the FTDI serial port device to communicate - this lets you do NFC dev using any Linux/Mac/Windows computer
We do have an Arduino library for both chips but you'll need to adjust any existing MAX6675 designs for the new MAX31855
This proto-board is the PCB you always wish you had
a piece of electrical tape must be placed onto the USB ports
2mm diameter drill holes are used so even parts with big leads will fit
0 megapixel sensor inside and an optical magnifier that can adjust from 20x (for basic PCB inspection) to 220x (for detailed inspection)
and 'act' like a NFC tag
PWM/Buzzer vibrational motor control
Operation outside this range is still possible - just the accuracy might drop a bit
you can use any microcontroller or driver
Trigger inputs can be connected directly to switches and buttons
