FIRST VISIT: The link to the Build List/Materials Needed
* Completely stock Ethernet module needed. (With Serial pin-out)
Arduino Type Here *NO* POE (Power over Ethernet) needed
* This has (2) PWM outputs and (2) PWM fan outputs
* Fans follow the PWMParabola as a percentage of the PWMParabola (fully automated).
-Or the fans kick on once the input of the analog signal reaches 300+ when using potentiometers!
* NTP time incorporated
-NTP primary server and backup NTP server implemented
* RA control via portal/phone app included.
* Corrected code for potentiometers to override PWMParabola to allow for manual dimming of pin 9 and pin 6.
-Return both potentiometers to "0" to have PWMParabola take back over...

Also, skim the code for "//" to make adjustments to suite your tank!
FYI: PWM output limited to 0-5v.
0-5v will give an output of approximately 50% with most drivers.
Op-Amp can boost to 0-10v (compatible with most drivers)
Op-Amp pinout for LM358:
Use below for security option (IF needed):
"key" must match on code and portal
This applies to the ReefAngel side of code...
Code: Select all
ReefAngel.Portal("username","key");
