These are switch mode power supplies which mean the output is regulated to 9v and the capable output current is much higher 1000ma.
Arduino 12v wall wart.
If it is 12vdc from the wall wart powering the neon device then you switch the 12v using a relay or possibly a logic level mosfet.
Yeah you want to connect your wall wart to the 5v pin and leave the vin pin disconnected.
Hey guys i am brand new to this arduino type stuff and am planning on buying an arduino uno tomorow.
Use google search box in upper right side of this page.
My cat broke my live nudes neon sign years ago so i can t experiment with that now.
I don t actually have an arduino nor have i ever used one my experience is with other mega168 based microcontroller boards so i m never really sure exactly what is brought out to headers and what the labels are.
Along with the uno i would like to buy a wall adapter to power it but the only problem is that i don t know exactly which wall adapter to get and i would like to know exactly which wall adapter to get.
