An Arduino board -- what is that?

The Westport Library will try to answer that question July 31 with a workshop on what a library press release describes as a "tiny, yet powerful microcontroller that has become a wildly popular, inexpensive tool for programming electronics."

The free workshop will take place at 7 p.m. in the McManus Room.

It is designed to show how Arduino boards can be used to work with electronic components and to developing coding skills.

The Fairfield County Makers' Guild will conduct the introductory workshop, and library officials say that for the first 20 people to register, the session will be interactive with participants able to use one of the library's 10 Arduino Sparkfun Inventor kits. Two people will work with each kit. Those registering after the first 20 will be able to observe and learn without having access to a kit, or they can purchase one from Sparkfun.com (kit 11227). Participants will need a laptop with the Arduino IDE free software installed before the program.

Online registration is required for the workshop at www.westportlibrary.org
