Wireless AC Light/Fan Dimmer with Bluetooth, Arduino & TRIAC

Project Credits: Electronoobs ( / @electronoobs )
....................................................................................................................................................................................................................................
In this tutorial, we will design a circuit using TRIAC and optocoupler to make a 220V Wireless AC Light Dimmer with Android Bluetooth & Arduino.
We have AC loads everywhere around us. And most of the home appliances are supplied with the AC mains power. There is plenty of situations that we want to have full control over an AC load such as a dimming of a lamp, speed control of AC motor/Fan, Vacuum Cleaner Control and so many other applications. The proper way to control dimming 230v AC is through phase control with a Triac: the Triac then is fully opened, but only during a part of the sinus AC wave.
But the controlling an AC load is not as easy as controlling a DC load. The electronics circuit for both these applications is different. The AC mains with a sinusoidal wave has the frequency of 50Hz. To build an AC dimmer, the zero-crossing points (the points where the wave changes its polarity) are important. To detect these points, we have to build a zero-crossing detector first. Similarly, we have to control the phase and cycle of the waveform. Since every component can’t tolerate 220V AC, so we need to isolate the circuit from 220V AC using some other component. The whole process is explained in the video & website link.

Very good 👍

[@tradingview5363]

expected constructor, destructor, or type conversion before '(' token
code error

[@Hercules159]

There are problems with this design, 1. If there is a problem with BT then you end up not able to on the fan, You should have a manual switch control the until. There is always an option for failure in electroncs

Hello sir I do this project same to same but on pcb Board
Connections are correct or same like provided circuit Diagram.
Still it doesn't work???

Can I use 150R instead of 100R and 4N35 instead of EL817?

[@HowtoElectronics]

Yes you can use 150R not an issue. And you can also use 4N35 but please go through the data sheet to verify 4N35 & EL817/PC817 equivalency.

Hey can I use it for dc led control instead for ac??
I want to use it for controlling light strip instead of a light bulb
pls help
BTW nice project though : )

Very good project .Please explain how to modify to add extra on off switch and eeprom for power off state remember for microcontroller

can I use arduino uno?if I use do i need to change the pins

[@jbalaji6895]

Sir please provide exact simulation circuit in Proteus

[@zzzzzzz1729]

is the process same for Hm-10 also?

[@HowtoElectronics]

HM-10 is BLE 4.0 whereas HC-05/06 is classic bluetooth. The same code might doesn't work.

Dear sir put one on/off button in the app also for bulb

I will do that with Nodemcu iot based ac dimmer.
