This Arduino library provides an interface for reading 3-axis analog acceleration data from the 7Semi ADXL335 Accelerometer Module. It allows easy integration and measurement of X, Y, and Z axis acceleration using Arduino analog inputs.
- 7Semi ADXL335 Accelerometer Module
- Arduino-compatible board
- 3 analog input pins (for X, Y, Z outputs)
- Download or clone the repository.
- Copy the files `7semi_ADXL335.cpp` and `7semi_ADXL335.h` into a folder named `7semi_ADXL335` under your Arduino `libraries/` directory.
- Restart the Arduino IDE.
| ADXL335 Pin | Arduino Pin |
|---|---|
| X-OUT | A0 |
| Y-OUT | A1 |
| Z-OUT | A2 |
| VCC | 3.3V or 5V |
| GND | GND |
ADXL335 Initialized X: 503 Y: 507 Z: 615 X: 498 Y: 506 Z: 610 X: 502 Y: 508 Z: 612
The output values represent analog readings (0–1023) corresponding to acceleration in X, Y, and Z directions. You can convert these to g-units using calibration.
- The ADXL335 outputs raw analog voltage proportional to acceleration.
- Sensor range: ±3g
- Calibration recommended for precise g conversion.
