PBP projects for R/C models

Question for you all.
What would be a HELLO WORLD for a 1/10 toy level PIC'd car?

Maybe one of the things you did for a Hello World?
Go to the end of a hall, turn around and come back.

I am considering doing a teach-the-teachers gig. The attendees would get Professional Development points. They should be allowed to take home their kitted cars.

The least expensive RC toy cars are about $25 retail. The most expensive thing in my present kits are the sonar sensors. What can I sense for less money?

Could a 'Nicera' IR Detector designed, "especially to detect body heat" enable my toy level cars to swarm together playing follow the human?

Imagine a teach-the-teacher class in a gymnasium where the HELLO WORLD application makes the students' cars follow the teacher as he or she tries to out wit it. (The teacher must be wearing a bikini while the students would all be dressed in their warmest winter finery.)

My 'All Electronics' catalog has IR DETECTOR for $3.90 each. Would this work? How sensitive are these things?

A light sensor would probably be the cheapest and easiest.
But the bikini thhhing is interesting...

How about something like this to get kids interested in microcontrollers?

[Kenjones1935]

That seems the best so far. I have some light sensors.

The teacher has an open 150watt incandescent bulb and an extension cord. Hmmmm....

Try again,

The teacher has a portable roadside emergency light. He or she runs around the gym, the toy cars follow. Maybe the gym lights need to be dimmed.

The fact that TOY cars have bang-bang controls ought not to inhibit the PIC control code.

I like it. Why won't it work?

What is this thing americans have about this fish?

Maybe the culture is different, but I really cannot understand it.

Anyway as a project has fun!

Are you sure your pickit is plugged in right because it should be verifying the I'd. Mine was verifying air, so that's why mine has that waring

[ScaleRobotics]

For what it's worth, on my Explorer 16, with a PIC32MX360F512L mpu:
It accepts the hex file (different one of course) from my Pickit2.
I can get a command line interface with my serial port (this chip does not have usb on it).
When I try to connect command line interface with my PicKit2, I get almost no response. I do get a square box at some baud rates, but that is about it.

Not a very good test, since there are a lot of differences, but it might be better to stick with USB for now.

scalerobotics - Mine looks just like yours!!

[Kenjones1935]

mine is C0D3
yours is C15A

Weird!

That came after I hit the WRITE button. I was asking it to load that .hex file. It seems to load mostly correctly, but comes up with that funny error.

The BIT Whacker schematic shows the connections from the 4 pin USB port [UBUS and USBID] to be different than the connections from 5 pins into J6 [PGB,PGC and RB2]. When "Writing Device PROGRAM FLASH and BOOT FLASH" it just sits there with the little red BUSY light flashing on the PICkit2 connector. Forever.....

I tried to use the USB port. Both to load the .hex file and to communicate. No success of any kind. Notta.

At least PICkit2 through J6 illuminates the blue POWER LED.
And apparently embeds the EEPROM.

I tried loading HELLO WORLD.hex. No luck at all. Same error message but no success loading EEPROM.

I do not know what to do. I can write fine in C. But I have no idea where or how to start. The only communication I get with the BITWhacker is with my PICkit2 USB connector.

I am getting discouraged. The only reason for leaving the original 16F887 was the cost of multiple PBP licenses. I really don't need the 32bit power just to move my robocar.
