Building an H Bridge

[er_name_not_found]

@magentaline

but unless you have a burning reason to roll your own

To learn, kinda like learning to make a radix structure even though you will always use one from a library in any real production.

I have checked Pololu:

Pololu - Dual TB9051FTG Motor Driver Shield for Arduino

And I'd like to attempt to build a good quad H bridge for under $40 which is their price point.
