Tell us about yourself!
That's right! The mosfet is essential regardless of whether the motor is small or large. Which mosfets would you mount? I would be thinking of two N-Mos (IRF640) so as to raise the output amperes (protecting the pwm outputs with appropriate resistors). Since the second NE555 acts as an H-Bridge there is no need for a P-mos. Let me know your changes. Thank you.
That's why my module doesn't give life signs.
