MotorShield on Due and external power

-

hi all,

i want use arduino motorshield drive 2 motors: 12v, 78ma max each.

the documentation of motorshield says: "if motor require more 9v recommend separate power lines of shield , arduino board on shield mounted."

is necessary , for?

to me seems easiest power motorshield 12v , let due recieve power through motorshield.

however, if follow recommendation, separate power lines , power motorshield , due separately: can use same external power supply both (i. e. 12v) or should power due 9v relieve voltage regulator of due?

many hints!

12v max can put regulator without heatsink.  if regulator hot enough, go thermal shutdown.

you should power due separately don't risk melting anything.

¿conocéis este proyecto? fvdw-sl 15.3 para raspberry pi. convierte la raspi en un nas. http://plugout.net/viewtopic.php?f=31&t=1880 llevo tiempo intentando encontrar la forma de hacer que una de mis raspberry se comporte como un nas. configurando samba, minidlna, transmision, ftp, nfs, etc. pues con esta distribución lo tengo todo hecho. lo instalé ayer y me tiene soprendido. ahora mi raspi es un nas, hecho y derecho. caracterísitcas. - interfaz web. que cambia en función de si eres el administrador o un usuario. - gestión de usuarios. puediendo dar distintos permisos carpetas y funciones. - gestión de carpetas - vpn - ftp - nfs - webdav - varios servidores dlna como minidlna, townky, etc - varios gestores de descarga como transmision, mldonkey, etc - gestión de periféricos usb como impresoras o webcam. - gestión de cron para automatizar procesos. - creo que se basa en arch linux. por cierto, estoy creando una tarea para que me exporte un archivo txt del dis...

hello, im confused uno r3, uploaded code quite few months in uno, working fine. now without having altered of circuits, trying upload code changes,im getting strange error "avrdude: verification error, first mismatch @ byte 0x0000          0x0c != 0x62" i tried research able solve issue,  im running kind of fuse bit being changed or clock speed altered, im pretty sure did not play around these items. any people, please . . thanks taz Arduino Forum > Using Arduino > Installation & Troubleshooting > avrdude: verification error, first mismatch at byte 0x0000 0x0c != 0x62 arduino
