I bought MinIMU-9 Gyro, Accelerometer, and Compass (L3G4200D and LSM303DLH Carrier) few days back. I am a novice when it comes to gyro and Arduino.
I connected it to Arduino UNO board as mentioned on polulu description page.
Since i was not sure, i didn’t solder the IMU to the connecting pins. I just connected them loosely on bread board.
I downloaded all required libraries and dependencies. But when i gave a test run, Unfortunately, it didn’t give any output. When i played with the open source code MinIMU9AHRS.pde for some time, i found that the code was not able to read any value from gyro or compass. I wrote a sample program to read and print the angular positions. But it indeed didn’t work.
So i have the following questions.
Do i need to solder the IMU with pins to get it work ?
If IMU can work fine without soldering it to pins, what other problems IMU might have ?
How do i check and fix them ?
I don’t have any circuit to check different variables. I need to get it work before next Saturday. Please Help.
Have a happy Thanksgiving.
