Story

In this small DIY project, we show you another example where Touch sensor is used as input device and LED bar as output device to LinkIt board. We show you five easy steps to interface the hardware and simple steps to code.

We are also explaining the code to you to understand each every line, what it means so that even the newbie programmers can also understand the logic.If you would like to see any improvements in the video series, please do let us know in comments section. The links to datasheets and other resources used in this course

Follow our video guide to see the steps in detail.
