• DIY WiFi LED Controller

With the arrival of the new aquarium, there was a need for a new light fixture. So, we present a super budget option under $10 with maximum functionality. The heart of the system is the ESP32 (dual-core processor) with 16 channels and 16 BIT!! Control via WiFi. Clock synchronization through the Internet. Temperature measurement of the radiator (in case of overheating, it reduces brightness). There is no display. There are no control buttons. Everything is managed through a phone or computer. The light fixture has a built-in web server. Over-the-air updates are possible. The drivers are homemade (I still have some boards available if anyone is interested). It has been in operation for about a month and works great. I will improve it as needed. I plan for a second ESP32 to manage the sump equipment. Both ESP32s will work together and synchronize when necessary. I have already purchased pH and ORP electrodes. A non-contact level sensor is included for automatic refilling. Plans include controlling the ozone generator and calcium reactor. We'll see how it goes.

There was a question in private messages regarding the driver and how to set the desired current at the output, so I will duplicate the answer for everyone. In the datasheet, there is a formula: R = 0.2/I, where I is the desired current in A. So, if 0.7 A is needed, R = 0.2/0.7 = 0.28 Ohm. Such a resistor is hard to find, but you can easily buy 0.15, 0.2, 0.3, or 0.33. For example, a 0.33 resistor will set the output current of the driver to 0.606 A, which is quite good for an LED. We are not pushing it to the maximum - the light output decreases slightly, but the heating is significantly reduced, as well as the lifespan.

Good, thank you, I'm thinking about how to repeat it. Where can I buy the A6211 or a ready-made 5-channel driver board? Regarding the program that controls all of this, it's quite unclear. And to better understand, what LED assemblies are behind the activity chart by time of day? The photo of the fixture shows 5 channels, but the graph shows 10. Is it really necessary to write out each graph for each channel so precisely? Thank you!

As an example

There are 3 such scarves left in stock, with 15 drivers on each. They can be cut as needed. If anyone needs them, let me know.

Hannah

What else is needed besides the ESP32 and drivers? Regarding the ESP32, from your other topics, I understood that a specific model is required. I will take the one from the link in the first message, but what else should I pay attention to? Thank you! P.S. You also ignored the question about the tape recorder. What about the program that controls all of this?

I bought the ESP32 from this seller - I have already checked 4 pieces purchased from him. I also used a converter so I wouldn't have to set up a separate power supply for 5V.

I will upload the firmware in a few days. I need to figure out how to set the access point name and password. Right now, it's hardcoded in the source code.

Catherine6534

for a quantity of 4 pieces - 22, delivery time 2 weeks

Off-topic, can I have a link?

Good evening, There are 3 such boards left in stock, with 15 drivers on each. They can be cut as needed. If anyone needs them, let me know.

What's the price?

Elizabeth882

I am also interested in the price of the board.

Jacqueline5976

I'm buying everything at full speed, I want to assemble. There's the inconvenience that I need to buy components for the drivers. In China, they definitely don't sell them individually. I haven't checked at the radio store, though. If anyone has a set of 5 to 15 drivers, I would take it.

Tanya

there is one last frag left maybe someone can offer something coral in exchange maybe someone has a neon seriatopora I lost my entire huge bush during the move ;(

Ricardo7341

What if there is no internet for a couple of days, how will people behave? Thank you.

Ricardo7341

Software clocks will run. They synchronize the time with the internet once an hour. Even if there is no internet after being turned on, the clocks remember the last hour before being turned off. That is, if the power goes out for a long time, the clocks will be behind. But as soon as the internet is available, the clocks will synchronize.

Good afternoon. Can I have more information about ESP32? Connection, firmware.

Johnny

It seems I miscalculated my strength.. I have three promises in the last three weeks and emptiness. I would pick up the topic, I like the idea. But I need a program, a connection scheme, and I also need an exact list of components for the drivers. Everything is on hold, half is purchased, time is running out. Alex?

Angela

Dear, do it yourself and share it. I will share my developments as they appear. I have a main job. For those who want a quick solution and don't want to delve into it, the direct path is to the store; there are many worthy brands. That's all for now. There will be a continuation, but there's no need to rush things.

Ross

My package has arrived... I am waiting for the continuation of the topic. Happy upcoming holiday to everyone.

Heather9815

Hello, did you order the driver handkerchiefs or did you buy them at the radio market?

Paul

drew and ordered it myself in China

Brooke

Is there nothing left? I would buy it, or a photo template? Yesterday I was making a control unit for devices at 220V, it seems to have worked out. Sent from my iPhone using Tapatalk

Aaron6112

Can you provide some specifications of your driver? Is there a board?

Karen2578

I fixed minor errors and re-uploaded. Negative numbers could be displayed on the graph... It seems I managed to eliminate the freeze after restarting the browser... I added color display for the numbers... The moon can be set in the code...

Sheila

Hello. I connected the DS18B20 temperature sensor. The standard libraries for working with temperature do not work properly. I added a daily temperature chart. It outputs a point every two minutes. The style and scale can be adjusted in the code. SSDP protocol has been added. Device discovery. (Computer -> network). Since we set a static IP address, this function is not needed, but it's good for the future.

Christopher7213

What are the next plans?

Veronica

I wanted to message you privately, but the email seems to be sent, and it doesn't appear in my sent folder. So I don't know if I wrote to you or not. That's why I'm posting here. I'm also working on a controller for ESP32. Take a look, it might be interesting. Here is its topic on the forum.

Leslie

The author disappeared, the topic died down. We never found out anything useful. It's a pity.

Omar3497

There was a need to make another lamp, so I decided to also create a new firmware for it. New version of LED light on ESP32.

Rodney7316

You can buy it here at that price and even cheaper.
