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

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.
