LED bulbs are widely used nowadays, they are great, energy savers, and because they are DC lights, they are also dimmable!
In this video, we will control the light brightness using CADIO dimmer device type, and as usual, we will not write any code at all!
All we need is a logic level mosfet, and of course, the LED bulb, this bulb is very popular, it's simply a 12 volts LED chip, came with an AC to DC power adapter, but from my experience, I prefer disconnecting it, and use the bulb as a DC bulb, and power it using my DC power supply.
We also need two pushbuttons. I will use this switch, which is simply two pushbuttons with a common pin.
Our circuit is very simple.
The mosfet gate is connected to GPIO5.
The drain pin to the bulb black wire.
The source pin to GND.
And the bulb red wire to the power supply positive line.
And of course, the power supply GND to the GND.
The two pushbuttons are connected to GPIOs 12 and 14.
In the CADIO info file devices table, we add a new device with the type dimmer, select the mosfet GPIO, and the switch GPIOs.
Our device will appear in CADIO app as a normal device, but when we open the device page, we can find this slider, with it we can control the light brightness.
Moving the slider will change the PWM duty cycle percentage, so we will be able to adjust the DC light brightness.
We can connect many bulbs of course to our DC power supply, and control their brightness using CADIO app.
The last brightness level we adjust is saved as a preferred level, and when we turn off the light, then turn it on again anytime, it will remember the last brightness level, and will apply it with this beautiful fade effect.
We can also use the switches to adjust the brightness, and the brightness level will be automatically synced with the app.
With the dimmer device, we can control the speed of any DC motor as well, for example, I can simply control this DC fan speed.
Depending on the load voltage and current, we may need to use a heatsink with our mosfet, because it may produce heat!
In the next video, we will talk about the unit overheat protection options, so if you are interested, subscribe to our channel, bookmark our website, feel free to try CADIO, feel free to contact us. - วิทยาศาสตร์และเทคโนโลยี

1st comment,
Best automation app in recent times
I loved it😍
Can please make A video about AC fan speed control with app and manual control 😊

I live in the UK, so how do I DIMM my 220v ac table lamp as I see this only works with low voltage, and what do I do with the esp8266, and how do I power it with 5 volts? I am using TUYA lamps that run on 220 volts AC at the moment and Zigbee to control them all, and my door sensors are battery operated, so to change to your system would be very hard, so perhaps you can explain in a video how to change.
How does the AC light work?
EEPROM IS INTEGRATED OR NOT ?
Just one question, the light widget changes colour when turning on or off but there is no text to show Light ON , Light Off or am I missing something? It is better to see text showing On/Off rather than just colour change which is sometimes confusing.
Thank you, this will be token into consideration during the discussion of future developments.
But is there a way to demer for 220 volt devices
Very good work.I think cadio is the esaiest platform I used ever. if I want to connect Atmega 328 in serial with Esp32
now I want to connect a dimmer to Atmega 328
can you please send me the arduino code to do that.
I want esp32 to communicate with ardrino. I have heard "cadio serial library" somewhere.
Can you make video on this
Make a vedios on cct type led
Great app works well with my 5 channel esp32 home automation board, it would be great if can include a IR Remote so can still control if no wifi similar to one made made by TechStudyCell
You can use remote controller! I will make a video about it very soon!
@@cadioHomeAutomation Thank you much appreciated
Will the be a point where you integrate this app with Samsung smarthings , similar to what sinric pro does?
We are planning to do it soon!
Sir maximum kitne appliance control kr sakte hai esp32 with extra mcu and manual swichea
21 devices
Hey how much voltage did you use for the led light?
12v
Hi Team
Plz make a video celing fan speed control(ac)
Thank You

Best app and easy to use, How to use AC Dimmer with PWM output and Zero volt cross as interupt?
In this case, you need an external MCU with CadioSerial library:
egycad.com/cadio/docs/CadioSerial-library/
@@cadioHomeAutomation There is nothing details about AC dimmer on that portal document, only DC Dimmer is there.
Great app! I will try every feature it has. But I wonder what is the frequency of the pwm signal? I hope it is more than 10 kHz. I don’t want it to flicker on camera.
I think the esp pwm is 1khz
@@cadioHomeAutomation the internet says it goes up to 40 mhz but I don’t know much about it. I will try though. One more question. Can I use push buttons to switch modes between on/off instead of a switch? I really want to be able to do that. I might even be a dealbreaker for me.
@@kerimturan1757 yes, just set the "switches mode" to "press".
egycad.com/cadio/docs/info-file/general-settings/#switches-mode
Having permanent licence means I can add as many esp board i want on single email id ?
Or do I need to get licence for every new esp board ?
Every esp should have it's own license ( the license is per unit "esp")
@@cadioHomeAutomation but in ai home automation video you said yo can have unlimited units if m not weong
Of course I didn't! Kindly check the video (at 09:00)
th-cam.com/video/h4RS7SxAisI/w-d-xo.html
@@cadioHomeAutomation oh ok u said we can link unlimited no of units to a single account,i thought this is a feature for premium users ,but still is thier any lifetime plan in which we can use multiple or unlimited units
Salam dear admin, Please add ultrsonic sensor (HC-SR 04), so that we can use it. I've shifted my old Blynk projects to this new platform, I really enjoyed it. JazakAllah.
Do you have an alternative to cadio?
I want an alternative, cadio doesn't give lot of customization 🙄
@@kakashiB2k Yes i'm using Blynk sice last 5 years, but you have to know about C++ for coding a project.
Sir one nodemcu 32 to controal 21 drivece with manual switches and sensors possible
Yes, using CadioSerial library
@@cadioHomeAutomation 1 vedio please
sir once you get permanent license you can use many nodamsu
No, the permanent license is per unit.
@CADIO Home Automation but sir I am use 3 nodemcu sir your launch app to buy license to use more mcu as possible as
In this case, you will need a license for each unit.
If you are dealing with a large number of devices, You can use the esp32, or use an external MCU with CadioSerial library, and you will be able to add up to 21 devices per each esp
@CADIO Home Automation thanks but extra mcu can oprat manual swich sensors possible 21 appliance
where can i get source code of esp32 dude?
Unfortunately not available
Ac support
i used another phone with same email id of my phone Cadio account... But now in my phone i can't control the light
Sorry can't understand! What does "id kn" means?
@@cadioHomeAutomation.
Sir esp32 connect Bluetooth
Unfortunately not supported yet
Can please make A video about AC fan speed control with app and manual control 😊
