How did you determine the value of the resistor for the ammeter?

@mrichardson23 or remove the backplate and replace it with a lcd-screen that can show different backgrounds :-)
nice vid!

cool

He says 1mA at full scale in the video wich is nothin :)

@zunayed001 you can do it even with a potential division law. chose any resistor, connect it to the ammeter, connect voltage and observe. if the voltage on across the resistor is 50% and across ammeter is 50%, they are the same. if not, change ur resistor and try again. of course it could be done by calculating using the voltage division equation..

so if we spam ur email account, the meter would always be at full.
:)
i think i am going to make one for facebook notifications
all i need is an ethernet shield since i already have the rest
where did you get the meter

Will you be updating the code for using EthernetClient to Arduino version 1.0?

@joemurphyjr I hope to get around to that soon!

Very nice! I was expecting to see a customized backplate for the meter, though, labelled "1 message", "2 messages", ... (or maybe on a log scale?)

@dancevideo2 I'd love to extend the project so that it has swappable backplates so that you can easily change the different scales you use.
