Corrected Diagram Active-low-High-Diagram-Correct_1png.png
What I had found: Whats this 100Ω resistor all about? There's a 100Ω resistor we use to connect the input pin to either HIGH or LOW voltage. Why is it...
I found this circuit on Arduino forum regarding Digital Inputs. This looks like a "safe" way to proceed. Any comments: Active-low-High-Diagram.png
We have just the HLT and a HERMS. The HLT has it own 30 amp 220 vac circuit. The HERMS is a 110vac 20 amp Circuit. Regardless, each is independen...
I have 2 probes on PIN 5 working!
You have a new user (Baldman)who needs his post approved in Hardware
I see in your sample code that you insure devices are off. Is there a reason? Are devices all not enabled when you close a brew day. Maybe a good i...
My proposed One Wire Setup. I would think it best to run a 3 wire from the Mega to a distribution box close to the probes so that the "weight" of the ...
Ok Port 13 will be easy to test. The reason I use Physical Switches is that I do not want to touch the computer if I can help it. It is very simple...
Why three different Probes? Because I already own them. I had Aubrin's Pids with RTD before the BCS. The BCS has its own Probes. The One wire are...
Ok I found the answer to the second question. You do need a 10k Resistor for switches that are NO and not set to Active Low. There is no need for ...
Think I am starting to understand more. I assume Active Low on a Digital Input is changing the input to NC (normally closed) so the Value would be "On...
Well I am setting it up on a small scale to do some testing of my scripts as I write them. I have four one wire probes and will set up a push button ...
I do understand about automation/manual control and displays. When I first got my BCS 462 I was able to display the Temps but little else. I know t...
Since they are independent, I would assume each Mega would be running its own Script. Can you call to Mega 2 :Script from Mega 1: Script? I would ass...
