is there any limitation to bluetooth baudrate?
is use bluetooth blue SMiRF silver..
one noob question, i use arduino mega 1280, and when i plug my battery i make a mistake by plug the vcc to the gnd and gnd to the vcc of the battery.. in result my arduino make some blast on the resistor (i think, the two brown box beside the reset pin).. =( =( =( is there any chance that i still can use my board? so far if i plug via serial cable and upload a simple program is no problem, but when i upload some long program the arduino just stay still and nothing happened plus the serial connection becomes weird.. is the problem comes from my program or is really the arduino is totally dead? =( =( =(
"Any serial stream from 9600 to 115200bps can be passed seamlessly from your computer to your target."
If small programs work on your Mega then it's not totally dead. It's most likely a problem in the longer program that is keeping it from working.
okay thank you.. as the result i unplug the 100u capacitor and the arduino mega works perfectly "for now"... is there any information that i can know what exactly the use of that capacitor? why it was put there?
There are 100 microfarad capacitors after the diode on PWRIN (to remove some ripple from the power supply) and after the regulator. Which one?
there are two capacitor, one near the reset pin and one near the power plug in right? the i`m talking about is the one near the power plug in..is that after or before the regulator? and if its thrown away, what could be the effect to my arduino performance?
