1  Community / Website and Forum / Control of format in Posting??? on: April 21, 2014, 07:32:22 pm
Hi Everyone,

I've been trying to find out how to better format things in posts. The editor icons show some obvious stuff. But I would really like to be able to better control placement of Images etc. If anyone can point to some how-to on this it would be appreciated.

So I get home some markup works, like BLUE etc.

And I figured out how to cut down the visibility of long URLs by doing Stuff like  THIS:

But images are always inline and take up lots of vertical space. So any explanation of them is hard to read at the same time. I WISH an image could be placed left or right and have text next to it. Any ideas?

Testing123:

This is some text that I really wish was aligned with the image. This is some text that I really wish was aligned with the image

So I can put the image left, center or right, but no text next to it.. Hmmm...

(That part above was done like this:)
Code:
[left]This is some text that I really wish was aligned with the image. This is some text that I really wish was aligned with the image[/left][center][img]http://arduino-info.wikispaces.com/file/view/Complete3-300.jpg/499207932/Complete3-300.jpg[/img][/center]

OK, no biggie and I don't expect this to look like Design News magazine, but it would be nice to have some better control. Many blog/forum systems do allow some formatting.

Any suggestions welcome, but it's not worth sweating too much..

Thanks!

Hi,
See a photo of the relay:


The relay COIL is rated at 12VDC and when you apply 12V DC to the coil the electromagnet inside the relay switches the physical contacts.

The relay CONTACTS are rated as shown on the relay.  One rating is 10 Amps (or LESS) at 30 VDC (or LESS) .

So you can switch 12V DC at up to 10 amps.

Reality Check: IF the load you are switching is inductive  (Like motors, solenoids, other bigger relay coils) you need to protect the relay contacts from the dreaded
Quote
A DC spark / arc could continue for some time, acting like a miniature welder and welding relay contacts together.

For solutions see the  article on the ArduinoInfo.Info WIKI HERE: (See the "Turning stuff ON and OFF).

Also, switching power loads can cause ElectroMotive Interference (EMI). See  THIS about That...

Guten Tag, Leo

Very good code in your example.  Its shows directly how to use the pressure sensor.

May I also put your code on the Arduino-Info.Info WIKI?  It does not now have any information on the BMP085 .

Viele Dank..

Easiest way to control that 12V power to the valves is with a small relay board.

Info on that and other Arduino Power Stuff on the ArduinoInfo.Info WIKI HERE:

Lots of info on Arduino controlling power on the ArduinoInfo.Info WIKI HERE:

The COM terminal on those relays etc. explained there.
8  Using Arduino / Sensors / Re: How to remove the transmitter from ultrasonic hc-sr04 sensor on: April 18, 2014, 07:34:34 pm
Has anyone been able to do something like this, where one Ultrasonic sensor unit triggers another to return a signal?

Usual echolocation requires a decent reflected signal echo.  Active response should work over a much longer distance.

I'd like to publish something like this on the ArduinoInfo.Info WIKI if there is a working example..

Hello Alehandro,

This happens to many of us sometimes.

"Everything is right but it does not work". 

This means "No, something is not right. You just don't know what it is".

Disconnect everything and carefully assemble it again, is what I do in this kind of case.

The photo shows an Electronic Brick with two outputs, one Analog, one Digital and 4 pins.

Which output pin are you connecting to??
