If you've ever watched an adult pay for something by simply touching their credit card to a machine at a store, or you've done the same with a bus pass, you've seen an RFID tag in action. An RFID (Radio-Frequency IDentification) tag allows a card to be read by a computer from a short distance away. This is very convenient, but it also allows criminals to steal information about you. For instance, on the subway or the bus, someone standing next to you can use an RFID reader to access the data on…

"Alexa, turn on the lights!" Sometimes it is easy to take the technology around us for granted. But have you ever wondered how a smart speaker like an Amazon Echo® knows what you are saying and how it can control lights and appliances in your home? It can seem like magic if you buy a device that just works when you open the box. In this project, you will learn how it works. You will build your own smart home device to control an appliance with voice commands using an Arduino®. Get…

How fast can a human driver react and hit the brakes when there is an obstacle in the road? Can autonomous cars react more quickly and make the road safer for everyone? In this project you will build your own Arduino robot and test human braking versus automatic braking as the robot drives toward an obstacle at full speed.

How fast are computers? How quickly do you think they can do 100 million arithmetic problems? Try this science project to discover an easy way to measure how fast computers have become and whether or not your computer is a math whiz.
Important: this project was originally written in the mid-2000's, and computers have gotten a lot faster since then! The project will probably not work as intended if you run the code on a modern computer.
