Please forgive my lack of knowlige. I need to make circuit with one button(normaly OFF, ON while pressing) using thyristor. This circuit will be connecting and disconnecting raspberry pi and bunch of LEDs(16x16 ws2812b panel) from power suply. I was imagining something like: pressing button first time: supply is connected, pressing button for second time: supply is disconnected and so on. I cant use switch instead( it has to be a circuit). I want one other led to indicate if its ON or OFF. I also dont know what values should i use for components. I will probably use 5V 10A supply but I dont know if resistors and thyristor survive that. Here is my wild guess:
I will appreciate any help. It shouldnt be mutch more comlicated than this(i found some alternatives with 2 buttons but i will prefere with 1 button). I am also sorry if missed something similar and this is a duplicate.
