Hi all,
I have been having problems using a Raspberry Pi PSU outside to power an Arduino Uno to close a chicken hut door. When the weather drops cold it stops working.
I could not find the problem until asking on this forum. Problems with Arduino working outside - Project Guidance - Arduino Forum
We want to stick with mains power, the cable has already been run.
Supply wants to be just a little above 5V. When opening the door is drawing 300ma, closing its 100ma. On stand by its just a few ma
Can you please suggest an alternate unit? Found this, but would I have similar problems?
eBay item number: 142750874296
I was thinking about using mains a laptop supply dropping the voltage to 12v for the buck DC-DC unit
Many thanks for your help
Dave
