1  Using Arduino / Microcontrollers / Re: Length between two Arduinos communicating w/ each other on: May 04, 2014, 01:40:52 pm
Well, I only need to transfer some boolean signals, so I will implement that with digitalWrite and digitalRead and use 3 or 4 long wires. That shouldn't make a problem.

Hello,

for my project I want to send data from one Arduino to another one. The problem is the distance, it's about 15-20m.
Is it possible to send data over such a long range? What do I have to care about and what protocol (I²C, SPI,...) should I use?

Thanks for your answers!

Nobody? smiley

Hi,
I have edited the original Leonardo schematic as seen in the pictures to have a smaller Arduino for my project.
I need both the ICSP for the AVRmkII and the USB for the Arduino IDE.

It would be nice if anyone yould check the curcuit for mistakes.

Thanks,
Max

I included that part from farnell and got some other errors from EAGLE:

I can ignore them can't I?

What about that:
http://at.farnell.com/molex/47346-0001/buchse-micro-usb-b-unten-mont/dp/1568026
I'll use this 'cause there's an existing EAGLE file... hopefully it fits to the standard DRC-file from BetaLayouts

Ah ok. Is the USB plug mounted onto the board? So there is no need for holes isn't it?

Is there an existing BOM for the original Arduino Leonardo? Because I'd like to take a closer look at the micro USB plug or can I use any micro USB plug i find on e.g. mouser?

Hello,
for my project I want to redesign the Arduino Leonardo into a smaller format. Therefore I used the original eagle file downloaded from Arduino.cc and edited it.

As soon as I make the Design Rule Check (with BetaLayouts) it says that there is an error regarding the USB plug. (as seen in the picture)

Can anyone tell me please how to solve this problem? Or shall I just order it in spite of the mistakes?

Thanks!
PS: There is also a mistake regarding the AD Converter...

Thanks for the answers, but I am looking for a display to use in a project as shown in the foto.

I should just look nicely, but there's no need for the reflective surface.

Hi,
i want to use this display with arduino:
http://at.mouser.com/ProductDetail/Lumex/LCD-S3X1C50TR-B/?qs=co%252bsI3njzXnmFIFs5WuecQ==

I already controlled it using shift registers (because there is one pin for each digit), but they bleached out after a time (I didn't know that I have to use 3-5V AC.

Does anybody have a suggestion?
Thanks!

I found another strange value for the inductivity L2: MH2029-300Y
What does that mean? Which L should I buy?
12  Using Arduino / Microcontrollers / Re: Arduino Leonardo Schematic on: February 19, 2014, 05:21:35 pm
And another thing: If I connected the VBUS with +5V, the atmega32u4 would also run (an be programmable) without an external power supply, right?
13  Using Arduino / Microcontrollers / Re: Arduino Leonardo Schematic on: February 19, 2014, 05:19:41 pm
Ah ok, that means I can simplify my curcuit.
So am I correct that I only need 2 22Ohm resistors and the 500mA fuse for the USB connection?

If so, I would take another look on my curcuit tomorrow and remove some unnecesseray parts.
It would be very nice if you could take a look at it then.

Thanks!!

I forgot the screenshot from the schematic
15  Using Arduino / Microcontrollers / Re: Arduino Leonardo Schematic on: February 19, 2014, 03:58:29 pm
But when I connect AGND, UGND and GND with each other, the part L2 is useless, isn't it?
