This was our very first Arduino Uno project. A bright LED that blinks!

This time, the light would only turn on if you made contact with the ball of Play-doh. The Arduino senses a difference in the electrons flowing through the circuit, then turns the LED on.

This is the same project as the previous, but with tinfoil instead. Tinfoil is more conductive, so no direct contact was necessary to cause a disturbance in the electron flow, only close proximity.

This is a thermometer created with a thermal resistor, created to save Ramsey's money for his chemistry class!

This is the middle of the process of building the Autonomous Car. All the wiring and programming is done, and all that needs to be done is the basic structure and the addition of wheels on the motors.

This is the final Autonomous Car. Small, agile, compact and speedy! Mikey and I originally intended to place two ultrasonic sensors next to each other to increase its field of view, only to discover that they interfere with each other and simply does not work.

Analysis

The Autonomous Car is most definitely a robot. It accurately reacts to its environment and avoids obstacles successfully and consistently, all the while flashing LED's when an obstacle is detected or when lights go out. It does what it was intended to independently. It was programmed to avoid obstacles and flash LED's, and thats exactly what it does, all on its own.

The Leonardo, as we're already doing, can be used to allow basic access to a keyboard for those with disabilities. It can substitute the small keys for large sheets of metal or even cups of water. This can be used for alternate controllers for games or machines that are remote controlled through a keyboard. The Leonardo only has six (?) available Analogue ports for six different keys, but I imagine you just need more boards for more keys!
