Features :

• High precision altitude with improved ms5611 code
• High precision vertical velocity with InvenSense accelerometer (optionnal)
• Screen display with Nokia 5110 : altitude, vertical speed, ground speed, glide ratio and more (optionnal)
• Ground speed and glide ratio with GPS device (optionnal)
• Flight tracking with SD card reader and GPS (optionnal)
• Bluetooth communication with external device (optionnal)
• Battery level (optionnal)

Where to start :

If you are new on the Arduino community. Buy :

• a breadboard
• an Arduino Board (Arduino Nano is good to start)
• a ms5611 + mpu9250 module
• a buzzer (with a 120 Ohms resistor)

And learn to compile the code : https://prunkdump.github.io/GNUVario/code.html
