In this section I am going to list a series of useful programs for electricity and electronics. Programs that will help us to create schematics, simulate, make calculations, graph curves, also some design tools.
LT Spice – Design and simulation of schematics
This program is very useful for creating electrical and electronic circuits, doing point of operation analysis in direct current, transient analysis and much more.
It’s the program we’re going to use to simulate some circuit on this page, so I made an article for this page showing how to install and create a simple circuit using this program.

WPLSoft – PLC Delta Series DVP
One of the official software for programming Delta brand PLCs.
Maybe it’s hard to find this program, so I’m going to leave direct links taken from the official website, if they stop working please leave a comment so I look for new links.

SciLab
This program is an OpenSource alternative to MatLab software for performing calculations, graphing functions, programming algorithms, and more.

Blender – 3D Design
With this OpenSource tool you can make 3D models and animations.
In figure 1 we see the 3D scale model of a stanco electric cabinet I made using Blender.

Foo Plot – Web to graph mathematical functions
With this website we can graph functions without installing a program, it is quite simple to use and you can graph several functions at once.

Draw.io – Schematic design
A simple OpenSource solution for creating quick diagrams and exporting to various formats.
