We love H-Bridges Right?

I put together what i think will work. Can anyone verify if this will work with an ardunio?

Thanks!
Sorry the Mosfets are NOT IRFZ48Z They are IRF1010N

No. Q1 and Q4 are at different potentials - up to 24V between them. How can they be driven from one transistor? A voltage which is low for Q1 may be high for Q4.

There are purpose-built MOSFET driver chips which will do this for you. They can drive extremely high currents into the MOSFET gates to make them switch very quickly. A 470 ohm resistor is not sufficient to switch at a reasonable speed.

Not very different from the schematic you posted here.

Post#23.

I told you there that the two top fets needed 10volt more on the gates than the supply voltage. Leo..

Anyone posing such a question should just buy something off-the-shelf. [ "ardunio" ]

Another DIY h-bridge project that might be worth a read.

Only people who don't know how electronics works could possibly verify this would work. Hang around long enough, and ask often enough, and you might find some one that says it is OK.

Thanks. I note in particular the suggested use one of these:

Which I was unfamiliar with, but is an interesting device well suited to the task.

Note also this:

The OP should note that switching an inductive load is fraught with pitfalls.

Guess the relays caught fire. Now some mosfet smoke is needed.
