You're welcome!

I am really sorry for the late reply, but the initial idea of the project was to make the castelated holes around the perimeter of the PCB as you suggest but the cost of manufacturing PCBs with castelated holes is significantly higher than that of normal PCB, so this was the reason I dropped the idea of castelated holes.

Thank you so much!

Hey Dimitry! Thanks for this tutorial, I wanted to know if the QR code algorithm of OpenMV would work on main dock, and if yes, how fast will it be compared to OpenMV if I don't use display output?

Thank You!

Thank you!

No, Dimming is a completely different concept, have a look at this excellent instructable for more details about dimming - https://www.google.co.in/amp/s/www.instructables.com/AC-PWM-Dimmer-for-Arduino/%3famp_page=true

Load voltage I used is 220V and Load is a 100W bulb, I do not recommend going beyond that without a heatsink on triac, but remember that heatsink will be connected to AC mains, don't do the mistake of going near it.

Congratulations !!

mikef14, here is my instructable on it--https://www.instructables.com/DIY-Solid-State-Re...here is the video tutorial--

how is it now better or worse?

How is it now?

I worked hard and published my Instructable -- https://www.instructables.com/GyroCube-Gyroscope-Controlled-RGB-LED-Cube/ I don't know why it is not getting attention.please help me and tell me what is the mistake I've done.

Thank you very much RomanDz for spending time for it and helping out.

Opps a huge mistake, I reversed the polarity everywhere, Thank you very much for pointing it out, edited it.

Glad that you tried! :)

I think by saying synchronization you mean zero cross detection, yes you can use it as dimmer in that way, but it is very complex for beginners to code microcontroller to detect zero cross and also because power MOSFETS(like irfp460) are cheaply available, so for the simplicity of code and circuit, I use them instead of using triacs.

It is a simple blink sketch, you can get it in examples in IDE, I used microcontroller only for testing, you just have to supply 5V to turn it on.

thanks!

That is not image it is video.

Glad that you tried!
