Arduino controller code for reef aquarium
Features:
- blue and white LED control through PWM signal
- FAN for LED dissipator
- funiture support FAN
- level captor and 12V Pump for osmolation
TODO : add schematics
LED Light ctrl : high speed (PWM) transistor switch circuit
Pump and fan ctrl : 12V Emitter transistor switch circuit with flyback diode
Level sensor : basic switch with internal pull-off resistor
LED : basic serial circuit with pull-of resistor for running check.
