What program would you recommend for designing electrical circuits?

Question

Electronics

I play with arduino, I want to move to a slightly more serious level

Answer 1

Once an arduino, then a number. Once a number, it means Proteus . He has good results only with the figure, on the analogue he can be weird. Qucs
is not bad for an analog

Answer 2

Altium, Eagle, PCAD, OrCAD - there is a lot of software. Of the cheaper ones, they usually use Eagle, the rest of the environments are for "cool" development. PCAD is no longer supported, but there are still many who work in it.

Answer 3

For end-to-end schematic/board design, Altium is unbeatable.

Answer 4

For PC, there is a free KiCAD (kicad-pcb.org), which allows you to draw both conventional circuits and multilayer PCBs.
For Android, there is a semi-free Electrodroid - draw directly from your phone. There is a paid simulation of the circuit (you can track the current / voltage on individual elements).

Answer 5

PCAD or Altium. PCAD, in my opinion, is less convenient, but many people work on it (if you are interested in the prospect of professional employment). Altium is more convenient, but expensive, so not everyone can afford it.
