| Jun 28, 2019 at 3:40 | comment | added | Donald | Other than using only 1 GPIO pin, is there any benefit to using a relay over an H-bridge? Specifically, I'm looking at a quad half H-bridge like the one here which should be able to drive both circuits. Looks slightly cheaper and comes in a smaller package, and wouldn't need an extra NPN. | |
