|Arduino Sketch (.ino) and libraries for the 3-Axis Arduino-based Seismograph|
ZIP package contains the single Arduino source file and the three libraries needed (Filters, RTClib & SdFat) for the Three-Axis Arduino Seismograph.
|DS3231-based Real Time Clock & Calendar module with mounting hardware and rechargeable cell|
A DS3231-based RTCC module with onboard I²C pull-up resistors and pin header interface. Included in the pack are two 10mm M2 Nylon tapped spacers and four 6mm M2 Nylon machine screws for mounting plus an LIR2032 rechargeable Lithium-ion cell.
Note: as this module has onboard pull-up resistors for the I²C bus, you may need to remove them, or avoid fitting pull-up resistors on the master, for it to share a bus with other peripherals.
|microSD Card Adaptor Module|
A small module with microSD card socket, 6-pin header, onboard 3.3V LDO voltage regulator and SN74LV125A buffer. Simplifies interfacing a microSD card to a 5V-powered microcontroller such as the Arduino Uno.
