I am using a uLCD32-PTu on an Arduino Nano with 3 Dallas Temperature DS18B20 sensors and a 2 Channel Sainsmart relay board.
Everything about my project works just fine, however, upon start-up and after the setup portion of my Arduino code has completed it's cycle, my relays both turn on and stay on until otherwise commanded to turn off through manual slider value adjustment, thereby activating the if statements. I have not added any statements to my code that would command the relays to go HIGH until the corresponding Slider reported it's first message.
How can I keep both relays off until the temperature reaches the preset slider temperature without any interaction with the device after start-up?
As you can tell from my code, I am setting my preset value from the Arduino itself upon start-up. All the controls on the LCD are for user adjustment IF preferred, but I want it to be a plug and play kind of thing.
Here is my Arduino code, let me know if you need any more than this to help me fix this issue... Thanks in advance!
