Interfacing 4 channel relay module with arduino

Using Arduino Project Guidance
1

hello guys please please give me information about my project
i want to make project The main purpose of this project is to provide continuous power supply to a
load, by selecting the supply from any of the four sources solar, wind, battery
and main power supply automatically in case one the source is absent.

please please please please please!!!!:sob::sob::sob::sob::sob:

give me code

ok thankk you very much sir

We need to know what the load is and what current it requires.

We need to also know how you expect to switch from one supply to the next.

5

Do you have budget and a software design specification?

6

are all your power sources the same voltage AC or DC and capable of supplying the same current load or will you be limiting the possible load to that of the lowest supply?

7

Since you give us virtually nothing to begin with, I'll reply with:

And move on. Good luck!

8

yes

i want to demonstrate a 12 volt bulb in class, and for changing source i use switches

10

for best demonstration i want to use 220 volt AC, 7 watt led bulb

I strongly recommend using a red LED, a resistor and two AA batteries.

For a simple demonstration, you can use diodes.

For manual control you use a rotary switch.

That is not a winning strategy.

If any of your supplies or loads are AC there’s a lot more to consider.
Read about Automatic Transfer Switches,
