Can It Be this SIMPLE?

Hi,

Wear a safety helmet!

With a full-face helmet or an helmet + protective chin cup
you will also provide protection to teeth.

Be careful!

Here the button "Go Faster" under the table was pressed!

What about using the PWM of the PIC?

Versatile DC Motor PWM Speed Controller:
(This example does not use a PIC to generate the PWM).

Part 2:

By using the PWM of the PIC you can set the right speed for the
child using the toy. (Next year you can set an higher speed).

This is done by changing the PWM duty cycle. By changing PWM duty
cycle you can set the motor to any speed and therefore create any
personalized acceleration curve.

(You will need a PIC with hardware PWM).
