Microcontroller Driven Safety Socket w/Remote Control for Your Lab
Ғылым және технология
A safety socket is a hazard preventing feature for your lab bench when testing devices connected to mains. This project started simple but, hey why doing this simple when I can do it much more complex? :)
So I used a microcontroller in place of a single relay to manage all the cool features this remotely controlled safety socket sports. A blinking pilot light indicates when the socket is on, and more lights indicates other statuses of what we can now call the "smart" safety socket.
The most important feature is that when power is out, the socket turns off automatically, preventing risks when the power comes in again.
This project has been amended with some changes that I've shown in this video: • Microcontroller driven... Please watch it for the required corrections.
This project is a must have in your electronics lab if you happen to tweak with devices that have to be plugged to the mains.
CAUTION
Working on mains voltage could cause serious
damages and kill living beings, including you.
** You MUST know what you do. **
Any showcased solution may fail, if you
replicate it you will do it at your own sole risk.
I shall take no liabilities.

I reckon the emergency switch should break the incoming mains. In the unlikely event of the relay terminals being fused/stuck closed the emergency button will have no effect.

Good point, but the emergency switch usually it is meant to control the relay. It is rated for 5A while the relays are rated for 16A. Also, I forgot to change the schematic, but I actually used two relays: one for N and the other for L. It is less likely that both relays get stuck. But again, your comment is spot on. Thanks.

Your point made me rethink some possible combinations that could indeed be dangerous. So I decided to review the circuit and I will post a new video with the necessary corrections. Thank you very much for your comment.
Watch the video with the amended circuit to respond to the possibility of having the relay stuck. Link here: kzread.info/dash/bejne/mY5hrrZrZrmwkso.html Thanks to @gregwmanning for the hint in his comment.
👍👍👍
first of all my salutation to you from which country you belong i want to make my son electronic repairing course under your supervision i am from pakistan give me your contact number thank you

Dear, it's a bit complicated. I think there are good mentors in your country. Thank you very much for your consideration.
