Modifying Kids RideOn Car

Projects General Guidance

1st Post... Zero programming knowledge other than the Arduino Uno kit.

Looking for advice / feasibility for modifying kids RideOn car. I've already upgraded the existing motors, but would like to swap over to the following Brushless DC Motor / ESC Combo:

Must retain cars forward and reverse, and I'd rather avoid using a potentiometer for the throttle. Ideally I'd like to use the existing throttle switch and programme the Arduino to "Soft Start" the motors.

FYI, I've played about with PWM already to soft start the brushed DC motor supplied in the kit, however, I have been unable to break the "Loop" to maintain full speed when the switch is pressed (Motor continually soft starts and slows down).

Any suggestions or guidance would would be appreciated.

Hi,
Welcome to the forum.

Can you post the code you have, it may be possible to work from there?

Please read the first post in any forum entitled how to use this forum.
http://forum.arduino.cc/index.php/topic,148850.0.html
then look down to item #7 about how to post your code.
It will be formatted in a scrolling window that makes it easier to read.

Thanks.. Tom.... :slight_smile:

Hi Tom,

I'm not home from work until Friday so don't have access to the code I was playing with.

From memory all I'd done was add PWM control to the "Motorized Pinwheel" tutorial, however, although I could control the speed at which the motor RPM increased, when full speed was reached the motor would slow and start ramping up again (Obviously not much good in a car).

Thanks,
Jim
