hey guys i got a picaxe 08 dev board thats got in/outputs varying from 0 to 4 and a V+ rail on one side and a 0v on the other side. i wired up an led to output 2 and 0v then wrote a little prog to make it flash. i then wanted to wire up another led on a different output and make the leds alternate. i can only get the first one to light up but never the second one. ive tried everything from flipping it around to hooking on leg to 0v and v+. im done rambling though i need some assitance. thanks!

No one can help you with anything unless you post a schematic of how you have things hooked up and the code for your program. We can't guess =)

I don't think you can use out 0 to drive a led use out 1 and out 2

Code:

Main:
high 2
pause 150
low 2
pause 100
high 2
pause 150
low 2
pause 100
high 1
pause 150
low 1
pause 100
high 1
pause 150
low 1
pause 100
goto Main
end

I don't know if you read this but it will help https://www.electro-tech-online.com/custompdfs/2009/12/picaxe_manual1.pdf

you probably burned out the LEDs because i didnt see you say you had any resistors on there.

Nice link Burt.... page 6 shows correct LEDs.
