While testing our updated Attitude and Heading Reference System (AHRS) library with a variety of IMUs, we found that there were not a lot of options for the MPU6500. So we decided to publish our own version. #MPU6500 #MPU6000 #IMU #arduino #library

We needed an instrument that can plot the voltage/thrust curve for any BLDC motor and propeller combination. We use Pulse Width Modulation to control the Electronic Speed Controller which drives the motor, and it would be nice to be able to relate the PWM percentage to thrust. Our first prototype used Force Sensing Resistors which will be compared to load cells. #arduino #fsr #dyno #shield

IMUs with 3 sensors each measuring 3-axes, pump out a lot of data. It can be difficult to work out how your IMU is performing, which is why the free open source data visualisation tool from x-io Technologies is so great. It is available for all major operating systems (Windows, macOS, and Linux). #arduino #imu #datavisualisation #datavisualization

This article explains how to write a C++ library to control and monitor the LSM9DS1 IMU sensor using an Arduino. If you want to really understand how a sensor operates, then write a library for it. It will take longer than you think, but the effort is worthwhile. This library can be downloaded using the Arduino IDE Library Manager or directly from our GitHub repository.
