Hello guys i need help.I am doing hand-made fair model for my little sister with aurdino but i need code for run carousel and Ferris wheel slowly.For example in the first start they are working slowly after that their speed is constant.I know it is simple but ı have no information about aurdinos:( if you help ı would be very thankful<3
An Arduino cannot drive a motor. You will need a driver like a MOSFET or H bridge. To choose a driver you need to know the motor supply voltage and stall (starting) current.
The motor speed can be controlled with PWM (Pulse Width Modulation).
Google “Arduino DC motor” for lots of info.
thank you for reply i will use basic 3v-6v 250 rpm dc motor.I found l298n motor driver.Is it okay?
