Motion Sensor PoC: BNO055 and Raspberry Pi Subtleties

The BNO055 is a capable IMU that has on-chip sensor fusion and filtering. Interfacing can be done using I²C and UART. When used with the Raspberry via I²C, you get erroneous measurements because of the I²C clock stretching bug of the Raspberry. Using the UART, results are correct.

Title Image Project: LED Controller

To create a lamp with adjustable color temperature and brightness, I use a warm/cold white dual LED strip, an ATtiny45 MCU with N-channel MOSFETs and two adjustable resistors. This article contains the hardware and software setup. The title image of this blog shows the project.

Short Introduction

Hi Internet,

since I play around quite a bit with electronics and software, and once in a while something comes out that might be of interest for the rest of the world, I decided to start this blog.

You may find here things about Raspberry Pi projects, Media centers, Home automation, Microcontrollers, Photography and a little programming, mainly in Python.

The blog will be updated on no particular schedule – whenever I think there’s something to share, you’ll find it here, but don’t be surprised if there is silence for several months.

Feel free to send comments on anything!
