    "what that line means is:if(true == bOn){ digitalWrite(RELAY_J1_PIN, HIGH);}else{ digitalWrite(RELAY_J1_PIN, LOW);}It is just a more compact way of writing it. And would have been easier to understand if I'd not been lazy and wrote it as:digitalWrite(RELAY_J1_PIN, (true == bOn) ? HIGH : LOW);"^this, thank you :-)

    Hey, I was looking to use the LM35 instead of the dallas temp sensor. Any reason I can't/shouldn't do this? I am looking to change this up a little, pumping the water through a closed system and a shoulder pad to have an ice-less ice pack. so, i was thinking putting the LM35 directly onto the water blocks to input the temperature, no need for water proof sensor. any advice especially with the code?

    basically http://www.bracestore.com/breg-polar-care-cube-col...this system together with yours. I am using a different pump as well. a 6V 600mA pump that i took out of the polar care cooler.
