I purchased the all in one kit from DFRobots that includes the ROMEO Microcontroller (ATMega 328). I try uploading the object avoid code into the Arduino IDE and I get this error:
avrdude stk500_recv programmer is not responding
I've searched and know I'm choosing the correct board and serial. In fact I've tried them all and get the same error. I've even changed the usb cable and same results. Others who have had this error say the board could be bad, I'm hoping thats not the case, any suggestions would help.
Below is my code I found:
OBJECT AVOIDING ROBOT CODE FOR ARDUINO - ADAFRUIT MOTORSHIELD - PARALLAX PING )) - TAMIYA DUAL MOTOR GEARBOX
CODE ADAPTED, COPIED, MODIFIED, AND STOLEN IN GENERAL FROM VARIOUS PLACES AROUND THE INTERNET BY GRINAN BARRETT JULY 4TH/5TH 2008
THIS CODE IS FREE TO ANYONE THAT WISHES TO USE IT, MODIFY IT, OR STEAL IT IN GENERAL.. HAVE FUN WITH IT!
This code will let you program a bot that will roam around looking for things to avoid running into. The code is pretty simple, but gave me major fits figuring out. Espeically the interaction with the
the parallax ping )) ultrasonic range finder. The main thing to remember is the intialization of the ping unit.. it has to be exact.. once i saw i was running to tight a loop on it.. things got much easier.. ( thanks collin)
if nothing else, this code will let you have the basics of a roving bot with ping capability, it's up to you to do cool stuff with it.
