Quadcopter, Construction (Arduino Aeroquad) (2011)

Arduino Quadcopter based on the Open Source Aeroquad.

The plan for this project is to add GPS based autnonomous navigation between waypoints for aerial photography and video.

Components: Arduino Mega 2560 (ATMEGA2560 MicroProcessor) board. AeroQuad Shield v2.0.7 with a ULN2003 IC (Darlington Transistors to drive external LEDs), 5 SparkFun breakout boards: Level Converter (3.3V-5.0V), HMC5843 Triple Axis Magnetometer, BMP085 Barometric Pressure Sensor, BMA180 Triple Axis Accelerometer, ITG-3200 Triple-Axis Digital-Output Gyroscope, resistors, headers and LEDs.
