Greetings, sorry if this is a stupid question, I'm new to this whole personal electronics stuff.
Situation: I have an IMU (Adafruit 9DOF copy) that I want to connect to my Arduino Uno R3 copy.
Problem: It just doesn't work, no matter what.
- For the Magneto/Accelero meter (LMS303DLHC) the fake "Who am I" part of the code returns the value 0xFF while the code expects a 0x10, so the sensor.begin() always return a false.
- For the Gyroscope (L3SD20) the "Who am I" part has a Wire.send; Wire.requestFrom; and while(wire.available()); (NOTE: it isn't Wire.send, but the #if Arduino >= 100 variant) where the while(wire.available()); code hangs forever and never retrieves any data.
Connections:
- VIN - 5V
- GND - GND
- SCL - A5
- SDA - A4
I'm using the Adafruit drivers from this tutorial: Software | Adafruit 9-DOF IMU Breakout | Adafruit Learning System
I have attached 2 screenshot of the construction. My last idea is that the casual cables put into the Arduino aren't closing the circuit properly, however I have bend the end of the cables so they expand and make proper connection inside.
And the link to the IMU is: https://www.ebay.com/itm/9axis-9DOF-IMU-Sensor-Breakout-Board-Module-Gyroscope-Compass/162834831759
EDIT:
- I have also tried swapping the A4-A5 cables, no success
- And I tried with 2 different Arduino, both produced the same result.
