Should I communicate to my XBee via the built-in Serial, or should I use Softserial/NewSoftSerial?

Also, in NSS, how do you select which pin is the TX and which is the RX?

Can an Xbee accept 5v communication signals from an Arduino without frying, or do I need to step them down to 3.3V?

I ordered a custom shield PCB not knowing that. Damn. 30 bucks down the drain.

I don't intend to have the board connected to my computer at the same time as the ID-12 is. Does the FT232 still transmit data to the ATmega 168 after a sketch has been uploaded and the board has been disconnected from the computer?

Can I use the  hardware serial pins that are built in to the Arduino as communication between my ID-12 Innovations RFID reader? I keep seeing people use the AFSoftSerial library to communicate with it, and I wanted to know why.

I think this is a joke.

Anyone agree?

Add a decent current supply for 3.3V.


Also, add the option of correcting the spacing between 7 and 8.

No, he's asking why the board doesn't have a 3.3V supply pin (coming from the FT232 or an external reg).

Ok, will look into that.

I just found some info about waypoint math here:

The area is my neighborhood, which has streets that are about 10 meters wide.

And by solely gps data, I mean operating just by using position info from the gps, and not using any external aides (Gyro, encoders, etc...)

The robot is land bases, btw.

I've been thinking about how to orient towards the heading using solely GPS data, and I can't figure it out.

I kind-of-sorta understand your explanation, but I get the gist of it.  ;D

Can you elaborate, though?


I had thought of something kind like your idea:
Program in the waypoint(s)
Boot-up and check location
Orient towards waypoint.
Begin travel.
Use some sort of ultrasonic or infra-red sensor to detect objects.
If an object is in the way, turn left or right (depending) and travel until the obstruction is no longer in the way.
Turn back towards the waypoint, and travel again.

I have a question:

Does anyone know how to do really simple GPS waypointing?
I'm trying to build a robot, and I want to include GPS.

I already looked through the code for the ArduPilot, but it's really confusing and has very few and vague comments.

There's a really old forum post covering this, but the websites don't exist anymore. Post:

And, if the price is too high for you when it comes to getting a mega, try waiting for when Liquidware has some more Illuminato's in stock.

I think the Arduino Mini is the best.
