One of the key aspects of physical computing is the ability to gather information about the real world. In order to do that, you must know which sensors are available and, more importantly, how to use them. This is precisely what the “Sensing The World” chapter of my upcoming book on physical computing is about. For a limited time, I am giving it away to all web developers who want to break free from the confines of the digital world and start exploring the physical world.

This (almost finished) free chapter will look at an array of binary and analog sensors that can drive projects. It will then explain in details how to use them in web-based physical computing projects: from the hardware all the way up to the software. It’s a great way to start learning how to interface with the tangible world.

Beware that the chapter has not yet been proof-read or copyedited in any way. It might contain errors and omissions. It would be very helpful to receive feedback from readers. You can do so by commenting below or by using the contact form. This is actually what I’m hoping for by releasing it early and free.

Note: by downloading the free chapter, you will be automatically subscribed to the monthly TangibleJS newsletter. You can always unsubscribe anytime.
