LSM303DLHC Magnetometer Help! POLOLU IMU

Hello All,

I have been working on an propeller based autopilot for a while now, and things have been coming along great. Although I was nervous about the lack of interrupts, the faster speed and multiple cogs have made timing the program efficient. I

Sensor Noise

Hello All,I am working on my first drone, using an E-Flite UltraStick. So far the build has been going well. I developed a system for switching between radio and arduino control. I am working on developing my PIDs. I got a decent bench test in today.

Radio/AutoPilot Switching Difficulty

Hello All,

I am working on my first drone using a E-Flite UltraStick. I have built up my code for retrieving data from accelerometer/gyroscope, and have constructed PID loops to set the plane to the necessary attitude as determined by the GPS. However

GPS Refresh Rate Problems

Hi All!

I have been working on creating my first drone. I began this project by testing my own arduino based PID controller. Then I moved on to actually installing the PID and accelerometer/gyroscope into an RC glider to test for level flight (http://

PID Controller - I2C Bus Noise from ESC

Hi all,

I am working on developing a PID controller designed to hold a levered arm level by controlling an EFlite outrunner motor. The idea being if I can hold one hinged arm level than with 4x the hardware I could make a platform fly. I am using some
