Welcome to the PICAXE forum.

Specifically which PICAXE chip do you have 08M or 08M2.
There is a preferred nomenclature for referening the IO pins.

What circuit board or other (eg breadboard) are you using.
Some of the Rev Ed produced PICAXE proto boards have a jumper that is moved depending upon whether you are programming or using the SerialOut pin as a general/digital output.

If you look at PICAXE manual 1 http://www.picaxe.com/docs/picaxe_manual1.pdf
on page 9 is the pinout for the 08M - ther SerialOut pin is also available for general IO as pin 0.
on page 10 is the pinout for the 08M2 - ther SerialOut pin is also available for general IO as pin C.0 (although B.0 will also work in the case of the 08M2).


Do you have the LED conencted between +5V and the PICAXE pin or from the PICAXE pin to ground/0V (in either case with a series resistor to lmiit the current)?
That will decide whether the LOW or the HIGH command will turn on the LED.

For simply turning an LED on and off you can then use the HIGH and LOW commands.
eg LOW 0 or LOW C.0 and HIGH 0 or HIGH C.0

Okay, seems you resolved the problem while I was typing a response. Good for you :)

However as you may see from my post, more information can be beneficial on receiving a clear answer specific to the problem at hand and save folks having to ask questions :confused: for more information .
