To make schematic diagram for project

To adding the schematic diagram how can i make it .It ask to using the https://fritzing.org/home/
but it is like paid one .any other option is available

One way to do this is to sign up and then click on the ‘I have already paid’ option. Not sure if it works all the time.

If you are on a Linux distro such as Ubuntu or Fedora, you may simply use the package managers(apt/yum) to install Fritzing.

Fritzing is a free software though. You may find the file for your system under the ‘assets’ section from their releases.
