Project Planning/Budget

There are 10 weeks given to complete this project. Within these 10 weeks, Chart A, below,
gives an accurate representation of what will be worked on, and when it will be worked on.

1) Research entails looking up items to use for the project, including which type of
Arduino to use, as well as accelerometer, breadboard, and LED lights. Also, it
includes how to make a ball, and how big the ball size should roughly be.

2) Mechanical Design includes putting the ball together by first making a prototype,
and then later on making the real thing.

3) Programming/Electrical Design is going to be putting the circuitry together, as well
as programming the Arduino to read the accelerometer, and to light up specific
LED lights based on the readings the accelerometer gives.

4) System Integration will be the combination of Mechanical Design and
Programming, by putting the completed circuits into the finalized balls, and then
resealing them.

5) Testing will consist of experimenting with the programmed Arduino, to see if it
properly reads the accelerometer’s readings, and executes the desired function.

6) The Final Report Preparation will consist of making sure our product works, and
preparing the presentation that will be given.

BUDGET

Arduino

The Arduinos will be used to process information obtained from the accelerometer, and 

depending on the reading that it receives, it will execute a function to activate a specific LED 

light.

Accelerometer

The accelerometers will be used to measure and differentiate when the ball is in free fall, 

being tossed, and when it hits the floor. Once the accelerometers measures a change in the 

acceleration, it will send a command to the Arduino which will determine which color the ball 

will shift to. 

LED Lights

The LED lights will be inserted into the balls and will light up between three different colors. 

Two of the colors will alternate after being thrown, say blue and yellow, so each time the 

ball hits a hand, the color will shift. The third color, red, will only appear once the balls have 

been dropped onto the ground.

Breadboard and Wires

The breadboard will connect everything together. It will connect the Arduino to the 

accelerometer and LED lights, so it will be the message center of the circuit.

Batteries
The batteries used will be 3V lithium coin batteries due to their compact size and formidable power output.
