Hi make sure the tx from gps is going to rx on arduino

Hi guys
Just check the lg service manual and the voltage is fluctuating voltage max 60 volt dc

Thanks grumpy mike thats what I was thinking. But I need to verify
that the voltage does go from 0 to 60 well I know the max is 60 volts
I havent checked with a scope to see if it getting to 0 volts or
if its in between.

Hi caltoa
yes its on the serial communication which is 0 to 60 volts
the rest is all ran by 250 volt supply. I work as a air con engineer
Just teaching my self electronics .

ghanks for your help guys

Hi guys

I have a air conditioning unit I would like to interface
with the serial signal fluctuates between 0 and 60 volts
dc what would the best way to interface with the arduino
Would a voltage divider be best or what do you guys think.

Thanks neil

You will struggle to control most ac units the way you would like. If you dont want to decode
The ir signals link up arduino to control the switching on the controller directly

I get most of my stuff on ebay some things dont take too long to turn up. If you dont mind waiting
Buy from chinese sellers they are normally cheapest

Hi im in the same situation been teaching myself.
As you can see by the data sheet all that chip is doing is
Controlling the motors. Apply voltage through the resistor
Circuit which I presume will be from your seperate board.
If you dont want to buy a scope as they are pricey. Use an
Arduino hope that helps a bit

Hi can you show your sketch for what you are doing. Pretty certain these
Phones use fbus

Hi try adding a delay at the end. The analogue read statement is reading it faster than yiu can blink

Thats cool im new to all this. Is that a logic analyser your using?

Hi its not rs232 signals it looks like differential signals and I've been thinking
It won't be able to be transmitted

Hi guys

Probably another stupid question from me again.

I'm an air conditioning engineer and I'm  working on a unit that has a wired
Controller being fed by a 2 core comms cable. I don't know what transmission protocol it uses.
So the questions are how would it find out?
2 could use hook a xbee to transmit from the cable(for the controller) to another xbee with the controller connected thus making the controller wireless
Thanks guys

That would be possible but you are asking for help on a arduino(atmega) forum

I know exactly how good hackers can be unless the original poster works for arduino or big company I don't think he needs to worry about hackers
