How do I give a radio control car autonomous control

Thank you,

I was looking for that include file, but could not find it.

The printed documentation gave me the details about the board wiring.

Onward and upward to bigger and better things.

GREAT!!!!!!!!!!!! Glad you got it.
Just for fun here is a "more advanced" blinky.
You might get something out of it. You can add the comments

'16F887 BLINK
   @ __config _CONFIG1, _INTRC_OSC_NOCLKOUT & _WDT_ON & _MCLRE_OFF & _LVP_OFF & _CP_OFF
   DEFINE OSC 4
   TRISD = %00000000
   CNT  VAR BYTE
   MAINLOOP:
   FOR CNT = 0 TO 10
   HIGH PORTD.0
   LOW PORTD.1
   PAUSE 500
   LOW PORTD.0
   HIGH PORTD.1
   PAUSE 500
   NEXT CNT
   FOR CNT = 0 TO 100
   PORTD = %01
   PAUSE CNT
   PORTD = %10
   PAUSE CNT
   NEXT CNT
   GOTO MAINLOOP

You used many previously defined aliases in the two INCLUDE segments as well as inside our Blink'n code;

'16F887 BLINK
@ __config _CONFIG1, _INTRC_OSC_NOCLKOUT & _WDT_ON & _MCLRE_OFF & _LVP_OFF

Where are these listed? On what page of which .pdf file?

At or near the end of Microchips *.inc file.

Can be found here
C:\Program Files\Microchip\MPASM Suite

This is the file that has pretty much everything about the chip in it.

The compiler did not like your @ line.

It felt that three of the aliases were unknown.

I commented out the whole line and the program compiled, programmed and worked exactly as I imagined it would.

I guess I have to investigate the items in the @ line.

Meanwhile I need to pick a light sensor chip for an incandescent light bulb. Got any suggestions? I have to purchase this on line. Our local Radio Shack has no such items.

Did you get an "over writing previous address" error or something like that? If so then I bet the Lines in the PBP *.inc file need commented out. But setting the fuses in thae inc is good too, personal preference kind of thing.

Light sensors. You should get a lot of feed back on that one.

Off the top...
I think you said that the car was going to look for a light. You may want to think about some small solar cells. Being a voltage is produced the ADC could read them directly, well it should if it is not so low a voltage as to not have a good resolution.

[Kenjones1935]

Yes,

It said something like overwriting previous address. It also did not like the comma in the @ line.

There is not a comma in the @ line... typo???
The overwriting previous address is from not have the config lines in the PBP inc file commented.

But if it is working...
