Executive Summary of Our Project Design

Our product is Test Board for Stepper Motor. The main purpose of designing this product is for educational kit for a university student. However to make the learning process more interesting, we design the test board for the stepper motor in the form of car control. The main component of this product is stepper motor, PIC microcontroller, encoder and LCD (liquid crystal display). Moreover to control the car control we are using wireless remote by radio frequency.

The car is built with three wheels. For this product we only used one stepper motor and it only control one wheel of the car and the other two wheels is used to stabilize the car. It means that our car only can run forward and backward. Since our purpose of design this project is for educational kit, we ignore the car control problems to turn left or right.

In technically, we are design circuit by referring to the books, internet and also by our own idea. Then we are using Proteus 7 professional to design the complete circuit. Moreover to interface PIC with the stepper motor and LCD, we are using C programming. The complete program is simulated in the MPLAB IDE v8.10 and it is transfer to the PIC using PICkit V2.55 program.

There are many experiments we are doing in a process of building this product. We are dividing our product into several technical parts such as encoder, LCD, speed control, remote control and also radio frequency. Each of the part is experimented separately and any changing will be done due to the time.

The stepper motor will be control by a remote control using radio frequency. The input will be send directly to the microcontroller and microcontroller will send the data to the motor drive. Therefore the motor drive will drive the motor. The output of the motor will be send to the encoder to calculate the speed and from the encoder, the speed will display to the LCD to display the output.
