Big Bother Big Sisters STEM Workshop and Mentoring – Part II

The second part of our workshop with BBBSLI will include the Raspberry PI. Here is another preview of the type of projects you can do with SpringBoard. If your organization is interested, please contact us at 516.414.2000. We (SpringBoard) put the fun in STEM Learning.

The Raspberry PI is a pocket computer. Yes, a really cool computer about the size of a credit card. For this project we will use the serial ports and a breadboard. Think of this as Engineering 101.

Raspberry Pi has a GPIO “General Purpose Input/Output” serial interface, that is composed of two parallel rows of metal pins. The GPIO provides an interface between the software and the physical world.

With these pins we can program the Raspberry Pi to interact with physical objects in the real world. We can receive signals from external sources such as a button or a device for measuring wind speed. We can also use it to control physical objects such as turning a light on and off or even operating a 3D printer. In this case The project you see in the photo below is the traffic light simulator.

After you learn how to connect the circuits on the breadboard, you will learn how to program the traffic light simulator in python. Pretty cool if you ask me. – By Tuly Reyes
