im getting errors 

 

Error 1 No overload for method 'Read' takes 1 arguments

 

Error 2 The best overloaded method match for 'Microsoft.SPOT.Hardware.AnalogInput.AnalogInput(Microsoft.SPOT.Hardware.Cpu.AnalogChannel)' has some invalid arguments

 

Error 3 Argument 1: cannot convert from 'Microsoft.SPOT.Hardware.Cpu.Pin' to 'Microsoft.SPOT.Hardware.Cpu.AnalogChannel'

 

Error 4 Cannot implicitly convert type 'double' to 'int'. An explicit conversion exists (are you missing a cast?)

 

Error 5 The name 'PachubeClient' does not exist in the current context

 

 

if annyone could please help

Use the intellisense help to see the arguments expected by your method.

Hi Ruan, welcome to the community

 

First of all please insert code using the code button in the message editor tool bar, makes it much easier to read and refer to as you have line numbers...

 

To fix issue #1 try removing the "500" from your call to Read. (should also fix issue #4)

 

It also looks like your missing a reference to the pachube library as well, try following the instructions on page 18 of the Hello Pachube sample pdf that should solve issue #5

 

Nak.
