Arduino Pro Mini (Deek robot) with power consumption and led.

[sundberg84]

Hello!

I have a pro mini (deek robot) with DHT22 and radio.
It runs out of battery VERY fast even though i removed led and all.

Every time the radio tries to transmit, a led by pin 9 lights up - and sometimes it doesnt send and the led keeps lighted.
What does this led mean? Some error i guess?

I tried to rewire everyting, but it didnt help - is it the radio or arduino board thats been shorted perhaps?
