Thanks a ton guys,
@brainfart - i am starting off by putting a gyro on a cheap heli and modulating the tailrotor to keep it from yawing - (http://www.ehirobo.com/shop/product_info.php?products_id=3307
) and then will proceed to add on things from there.
@Daniel - Thanks for the info. Good point on the low dropout voltage regulator! thnx. I have a stupid Q regarding the crystal (see #6 below)
@Neilzero - Thanks for that page. It REALLY helped me get a better understanding of most of the concepts of standalone atmega, and a lot of the links on the page were useful too!
Here are a few more Qs i had -
6. Heres the stupid Q - if i use the atmega's internal crystal/oscillator, which i have read is equivalent to 1Mhz, would that mean my atmega will be running at 1/16th the speed compared to if i used an external 16MHz crystal? (So in a sense a 16MHz external cryztal is "overclocking" it?)
7. Mellis mentioned that you can use a Wiring board (which i have) as an AVR-ISP (http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1158265039/5
) Where could i find info on that ?
8. If i program the atmega168 via wiring board, will it be able to put a bootloader on as well as upload the program i write? or will it only do the bootloader and i will have to put it in my arduinoNG to upload the program ?
9. Any useful links of people using gyros with their own microcontrollers in helicopters? or for anything else?
10. Would i be correct to assume that a gryo will only show a rate of change if there is rotational movement about its axis, and not if it is moved around on a horizontal plane without any rotation?
And also, if you guys could help with Q1 & 2 from the original post
Once i have that figured i will buy my mini! (also would like to buy one of these!! > http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1167665675
Thanks a lot,
Really appreciate the help,
