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.
In the first part of our tutorial we explored the anatomy of a Symfony2 deployment and how we can use Chef in Amazon OpsWorks to manage and deploy a Symfony2 application.
In this tutorial, we are going to explore OpsWorks’ core concepts and deployment lifecycle.
Created by Makeblock, an open source “Lego for adults” arduino robot building platform from Shenzhen, Me Orion and mCore are two boards based on Arduino UNO, which we are thrilled to welcome to our family of supported devices.
Ever since codebender started growing, one of the biggest challenges we faced was pushing updates to our compiler and being able to quickly iterate on it, fixing bugs and improving its performance. Since we’re kind of obsessed with making all of codebender’s users happy, we need to make sure that all changes applied to the compiler won’t break existing sketches. After all, what’s a web Arduino IDE if you can’t compile your code in it? As of today, about 70000 users have registered to codebender and it hosts more than 200000 projects. How can you make sure all of them work fine without having the whole testing process last forever?
In our blogpost today we will show you how you can create a simple installer application with the help of PackageMaker. The installer will install a kernel extension file to a Mac OS X with a version greater than or equal to 10.9.
