In this tutorial we will create a currency converter solution that shows the conversion from USD to other currencies on...

 

I've hacked my already hacky B4AHelp program to give tidier results when looking at B4R Xml files.

EDIT: Updated to v1.1 to overcome a change in the Xml format that I just noticed.

Hi,

based on previous Analog Read Example extended the solution by using the Arduino Ethernet Shield to send temperature data to B4J server and receive confirmation.

The following data types are available in B4R:

Numeric types:

Byte: 0 - 255
Int (2 bytes): -32768 - 32768. Similar to Short type in other B4X tools.
UInt (2 bytes): 0 - 65535.
Long (4 bytes)...
