Team #2 Project
• Our project is a remote control
car, that can display battery life
speed and direction, and can
turn on the lights at the flip of a
switch or if it gets dark.
• The benefit to the user would be
a better remote control car
• There are similar types of
products, however we are the
only one that has all of these
features.
• Our product would fall under
the consumer industry
• Picture from

318-595 Capstone Project
Project Features
• The remote control car has a two-way antenna that
can transmit to and receive data from the car.
• Control of the car will come from the controller.
• The car can turn its lights on and off manually, and
automatically if it gets dark enough.
• The display will tell us the speed and direction of
the car, and the battery life remaining.
