Building Artificial Neural Networks

Building Artificial Neural Networks with Arduinos
A 1-2 Week Curriculum Unit for High School Biology & AP Biology Classes.

In this unit, students will explore the applications of artificial neural networks, especially in the field of artificial intelligence. Students will learn about the history of artificial intelligence, explore the concept of neural networks through activities and computer simulation, and then construct a simple, three-level artificial neural network using Arduinos to simulate neurons. After building the network, they will be challenged to discover how altering the connections or programming of the “neurons” alters the behavior of the network. Finally, students will explore the ethical implications of building artificially intelligent machines.

Some of the lessons in this unit feature special equipment, including Backyard Brains’ The Claw EMG gripper hand, microcontrollers (i.e. Arduino Uno), and circuitry components (e.g., breadboards, jumper wires, resistors, photoresistors, LEDs).

The lessons were developed by Lawrence Bencivengo Jr. of Mercer Island High School (Mercer Island, Wash.) and Benjamin Hart of Redmond High School (Redmond, Wash.) as part of the 2015 CNT Research Experience for Teachers program.
