Walk Hard: Designing a Pedometer
Format
SOECS Senior Project Demonstration
Faculty Mentor Name
Cherian Matthews
Abstract/Artist Statement
A pedometer is a device used to count the number of steps in order to estimate the distance that one walks or runs. A step is defined by the group as one-directional acceleration. In other words, a step is counted if the user picks up his/her foot and sets it back down. The group will not distinguish between a walking step and a jump. The pedometer to be designed must be able to count and archive steps. The steps will be displayed on a personal computer along with an estimated distance based on a hard-coded average step distance. The pedometer design will be based off of the University Tool stick Starter Kit with the C8051F020 microcontroller, .a two-axis accelerometer, and a LCD. The final project will be encased and have the ability to attach to the hip of the user. Testing of the prototype was conducted through the use of a team member in order to set the threshold of the accelerometer which is being used to count the number of steps. Software was written in the C programming language and the SDCC compiler was used to compile and link the code. All hardware schematics were produced in AutoCad and the assembly of the project was conductedusing a perforated board, battery case to distribute power, and wire wrap. The final project is able to successfully count steps and display the time, steps, and distance to a LCD.
