Meerwasseraquarium Led Beleuchtung Selber Bauen

The following post explains a straightforward ambient light dependent led illumination controller circuit. The light fades or intensifies proportionately ich response to die ambient irradiate conditions. With brighter daylights, the führen zu illumination it s okay softer and vice versa. The idea was requested by one von the devoted members des this blog.The Request

Dear Sir,While search through die internet zum a fully automated day/night angeführt Time Controller, i found your blog und I was wondering if freundin could help me with in advice. Ich want zu add some kind of controller to give me smooth shift from sunrise/sunset of an aquarium led lamp und with what ich found on internet so far, seems way auch complicated or just expensive weil das my goal.I was looking for something simple, without ns need des simulating a thunderstorm through in Arduino board with n channels i will never ever use. Ich want other that could light up some LEDs punkt a provided time if fading other LEDs, all with a smooth transition. And this has kommen sie repeat twice a day, every day.What do freundin say, kann you aid me?The lamp ich have, zu sein the one indigenous ... configuration:- weil das daylight12 ns Cree XP-G2 R5 - 6500 - 7000K4 x Cree XP-G2 R2 - 2700 - 3200K2 ns OSRAM SSL80 Hyper Red- zum night time2x CREE XP-G R2All associated through 5 x KSQ 400mA (with die maximum des 6 LEDs bei a row zum each KSQ 400mA) to a laptop energie adapter.Now, ich don"t know if mine LEDs have dimming capacity or I have to happen them v some dimmable drivers to obtain die desired effect.Also, ns systems i found deswegen far, are all based on a Arduino and they it seems to be ~ bulky. Ex. Neptune (Apex), Profilux, Reef Keeper, DIM4So, the being said,thank you in advance for any help.

The gezeigt light dependent led controller circuit ist basically a light dependent PWM optimizer circuit who duty bike varies in accordance with ns potential difference or level weist itscotrol pinout.As kann be seen ns circuit has a pair 555 ICs. IC1 is configured as a standard astable having actually a frequency des around 80Hz. This frequency ist not crucial bei terms von the circuit functioning.IC2 is configured as a PWM generator such the it compares die square wave signal punkt its pin2 and the triangle wave across its pin6/7.

This results in in output through a certain PWM content at pin#3 des ICs.However this PWM duty cycle can be varied merely varying die potential difference at pin#5 des IC2.An LDR can be checked out attached across a potential divider preset at pin#5 des this IC. Die preset kann be used weil das fine tuning die results together desired.The LDR resistance level jetzt determines und varies ns potential across this sensing pinout which an turn results in a proportionately varying duty cycle punkt pin#3.The varying duty cycle causes the connected transistors zu conduct accordingly and produce the correspondingly varying intensities over die connected LEDs.The two transistors room configured together inverters i beg your pardon ensure the contrary responses end the led sets linked across the collector des the corresponding transistors.
