Hi,
i have found this cool guide on retrofiting the esp32 Cam module to a toy car and it seem fun and usefull,
i am a noob on coding so i need some help
the code is below, but i need to change it so that it would utilize only one motor for back and forward movement, and a second (step) motor for left and right controll.
i am using esp32 cam and L298N motor driver
does any one have any expirience with this
