Good news, everyone! We are partnering up with Seeed Studio and SparkFun, to give you even more Arduino awesomeness! And it was just the right time to announce this, as the Arduino Day comes in 2 days, and this is just the right way to celebrate it!
Hey there! Did you notice our new Homepage?
We went for a better dashboard experience and for a more detailed overview of your Sketches.
Let’s take a look at all the changes in detail:
Maybe you’ve been using codebender for a while and have had great success making things. You write the code, click the magic ‘Run on arduino’ button and a few seconds (and some blinking LEDs) later your board is programmed and you enjoy the fruits of your efforts. If you have ever wondered how that generated machine code gets its way into your board, this article is for you.
In this tutorial we will use the Adafruit BMP280 sensor. This sensor can measure barometric pressure and temperature with very good accuracy. Because pressure changes with altitude we can also use it as an altimeter with ±1 meter accuracy! Accuracy for barometric pressure is ±1 hPa and ±1.0°C for temperature.
