HOW CAN I...?

Question

hi.how can i drive a DC motor with L298?Who can tell me what is PWM & HOW can i use it to drive a DC motor ina ATMEGA32?

Phil Hobbs · Accepted Answer

I suggest attaching a sprocket to the DC motor, and turning it using the L298 as a pawl.

PWM is "Pulse width modulation". You can use it by turning the DC motor using the ATMEGA32 in the above matter, but using longer or shorter strokes depending on how fast you want it to go.

Alternatively, you could read your textbook or show up to the lectures.

Cheers,

PWM is a method used to control the speed of the DC motor by turning the power to it on and off very quickly. The Atmega32 will do this for you once you program it. The L298 sits between the Atmega and the motor since the Atmega is not capable of supplying enough power to drive the motor directly. Look up the data sheets on the Atmega32 and read the PWM section.
