Regarding Fritzing schematic

I am unable to find bolt wifi module and single channel relay module parts in fritzing for connections. Please help.

Hiiiā€¦ @dheerajswaroop15, you can also draw diagrams on Draw I/O.

How to get the components?

either you can use the components from the library
or else you will found a lot of component online on some web portal just search for the Fritzing components and download them and use them
