Open Source
Reef Angel was the first open-source aquarium controller out there. You never have to write a line of code, but if you want something custom, like lightning storms or tide effects, you’ve got full access to the hardware and software to make it happen.
It’s built on Arduino, which is about as proven and reliable as it gets. You get a rock-solid controller running your tank with plenty of room to make it your own.

PWM Dimming Signal
PWM (Pulse Width Modulation) signal is a digital signal where you can achieve dimming by altering a square wave form.
This square wave form can be viewed as a pulse and changing the width of this pulse increases or decreases the dimming signal percentage that will be applied to your devices.
Example of devices that can be dimmed with PWM signals are: Meanwell ELN Series -P drivers, Meanwell LPF Series drivers, Steve’s LED drivers, LuxDrive FlexBlock drivers, LuxDrive BuckBlock drivers, PWM controllable Fans and Jebao controllable pumps.
Analog Dimming Signal
Analog signal is one of the oldest type of electronic signals. It has been around for decades and can easily be achieved with a simple potentiometer.
The dimming signal percentage is increased or decreased as the voltage on the analog signal increases or decreases.
Example of devices that can be dimmed with Analog signals are: Meanwell ELN Series -D drivers, Meanwell LPF Series drivers, Inventronics drivers, Kessil LED fixtures, BuildMyLED fixtures, Apollo LED fixtures, JBJ LED fixtures, Jebao/SpeedWave controllable pumps and Tunze controllable pumps.
