We’re excited to announce that codebender has been acquired by Codeanywhere!

We launched codebender 4 years ago to make it easier for you to develop Arduino code and build your next amazing gizmo, product, or hobby project. Since then, we’ve had 100,000 people use codebender, and more than 300,000 projects hosted on the platform.

Test Automation overview

The use of special software to control the execution of tests and compare the expected results with the outcome provided by the tests, is called test automation.
With automated tests we can automate repeated actions which are time-consuming when performed manually, and ensure the functionality of our code. Test automation is critical for software development teams which produce software in short cycles in order to ensure that the software can be reliably released.


In this tutorial we will use the Adafruit TSL2561 sensor to measure LUX with Arduino.

The TSL2561 luminosity sensor is an advanced digital light sensor, ideal for use in a wide range of light situations. Compared to low cost CdS cells, this sensor is more precise, allowing for exact lux calculations and can be configured for different gain/timing ranges to detect light ranges from up to 0.1 – 40,000+ Lux on the fly.
