Connect 3 step motors to Arduino Mega using L298H bridges

Hi, maybe I need some help.
I want to connect 3 step motors to Arduino Mega using L298H bridges and one magnet and one camera.
Can somebody check it and tell me if it is ok?
Thank you very much in advance!

You would be best to upload the sketch (the .fzz file) instead of a picture as we can then look at the sketch in detail. My first suggestion would be to dump the L298Hs. They are transistor rather the DMOS drivers and thus have about .6 to .8V across the collector when fully on which causes heat (thus the large heatsinks.) A stepper driver such as the A4988 or DRV8825 (both in core parts) would be a better bet. You also need to verify the driver will sink the amount of current required by your motors.
