173.4.5 LCD DisplayFigure 3.7 LCD DisplayLCD Display was used as an error debugging tools for displaying theinformation we wished to see from the system. Figure 3.7 show a 16x2 LCD displaythat was used in the project.3.5 Circuit DesignThe circuit development for Micromouse will be consists of the main boardand motor board. Both of the boards will combine with the other hardwarecomponents to work as a system.3.5.1 Main BoardThe main board can be considered as the brain for the <strong>robot</strong> since it consistthe PIC18F452 microcontroller. Figure 3.8 shows the characteristic tables and pindiagram for PIC18F452. Beside of the microcontroller, the board consist all the othercomponents such as the voltage regulator, pin connection to the power supply,connection to the motor board, sensors connection, and other basic electroniccomponents. The main board can considered as the main control unit for the <strong>robot</strong>since all the signals processing will be done on this board.
18Figure 3.8 Characteristic Table and Pin Diagram for PIC18F4523.5.2 Motor BoardFigure 3.9 UCN5804Motor board was used to control the high voltage and current to the steppermotor since the microcontroller not affordable to supply high voltage and current tothe motor. Motor board was mainly consisting of the UCN5804 unipolar steppermotor driver which shown in Figure 3.9. The driver will receive signal from the PICand operate the motor to move or either stop. The basic connection idea for the motorboard is shown in Figure 3.10.
