Hello, So the problem is what you use to control the light. I don't know if you use a relay or a triac I have to see your schematic in order to give you more helpful information. I have designed system that work on AC voltage before and MCUs that control the AC voltage You can have a look over my portfolio and reviews.

hello i made the same circuit using arduino, the main problem was zero crossing detection , you can solve this using H11AA1, the dimming rang from 0 to 100%. we can desgin it using potentiometer, or push buttons as the video shown.

i can help you with this your circuit is flickering because you are not having perfect zero crossing . i have done more than 20 projects in which i have to perform dimming or speed controlling by controlling firing angle of ac.

Hello, I am doing a similar kind of project like this right now (actually it is a small part of my ongoing project :p ). If you award me the project, i need to clarify some things first, 1. What type of Bulb / Lamp are you going to drive ??? Because the bulb in the video you linked with the project is an Incandescent Bulb. 2. What are the required things when the project is completed, i meant a) Working Video b) Working Video + Schematic c) Working Video + Schematic + Hardware shipped to your Address It's all i need to know till now, if you feel that you will award me the project, feel free to knock me for more discussion regarding the project. Thank you. Best Regards A N M Muntasir Hossain Tonmoy Skype : tony67_bd
