3.1 PIC16F876 Microcontroller
The PIC16F876 is the “brains” of the Drive Subsystem. Using built-in RS232 interface, we were able to use two pins for transmitting (from user). We were able to check what inputs were coming in from the user and then decided which signals to send out to move the motors. By using the built-in Pulse width Modulating channels, we were able to control the speed of the two D.C motors at the same time. The remaining pins were general input and output pins and were used for outputs to control the stepper motor and D.C motors direction.
