17 | Measure altitude with the BMP280 barometric sensor

Full code and manual on GitHub: github.com/CarbonAeronautics
In this video, you will learn how you can measure the altitude of your quadcopter drone through the use of the BMP280 barometric sensor.
The purpose of this video series is to learn the basics behind a quadcopter drone and enable you to build one yourself, by dividing this challenging project in several easy-to-understand parts. You use the capable Teensy 4.0 microcontroller together with the easy-to-use Arduino language.

excellent video. youre a great engineer. thanks.

Great work !!!, what education program can you recommend for someone to have such powerful knowledge and skills as yours!?!?!? it's really amazing

[@VPaulGreenwood]

Love your videos, helping me a lot. Really like the straight forward approach with demonstrations and graphs and code all inline with no unnecessary side talk. One thing I’d like to point out is that “0x”, like in “0xA7l, is notation that A7 is a hex number. It’s not zero-times anything. So I’d say, “Hex A7”, not “Zero times A7”. In the same way, “0b” indicates binary, so “0b0101” would be “binary 0101”. It’s a weird nomenclature. I’m not sure how it got started. I wish I knew what the zero before the letter was for. I wish it was a dash or something else. Maybe someone here knows???

Thanks for the remark, I didn't know!

I think the syntax comes from early Unix, AT&T assembler and the C programming language. This is certainly my recollection from learning C in 1986 at university. More details on wikipedia: en.wikipedia.org/wiki/Hexadecimal

when will you update the PDF manual

[@Zeemer1998]

Hello, what about outdoors configuration ...
Will it be enough just to replace the barometer BMP280 with a more accurate one or, for example, configure BMP280 for outdoor? Is it necessary to change the approach in formulas and calculations?

[@henrithiesen8054]

I have trouble run this code with an Adafruit BMP280 on wire1 setting something I miss. No problem to run the adafruit test example for bmp280 on wire1

[@trarredbandit9734]

I never expected you to add a barometer to the drone. Usually people stop at the IMU for arduino drones. At this point, will you be incorporating a GPS and/or Compass?

[@carbonaeronautics]

Thanks! I will try to incorporate a gps as well, as soon as i have found one that is small enough and can be connected with I2C

[@trarredbandit9734]

@Carbon Aeronautics Great project so far. Also for more understanding of the GPS and Compass, I recommend watching the video made by Joop Brooking and his
STM32 GPS flight controller.

i can't find the full code on github please someone help

Lmao I’m making a model rocket control system but this is exactly the stuff I’m using

[@compilingthechaos]

Hey, I am also making a model rocket and i wanted to know that which sensor are u gonan use for altitude measurement and is it precise or not?

[@theblobewab6844]

@@compilingthechaos Im making my own custom board now that im further into development but for the IMU im using the LSM6DSO and for the barometer the LPS22HH, def not fully precise especially because aerodynamics around rockets but when combined with an altimeter it's good enough for what im doing
