This circuit diagram is very simple but I dono does it work?
M is motor. D is diode. R is resistor. L is light (LED or no polar LED or bulb)
It won't light up when the car forward. it ll lig ...
It won't light up when the car forward.
It may not be feasible .LED still light up dimmer when car move forward .
When your car move forward ,due to the ESC switching at high frequency and so the motor will generate back emf .So it still have some forward basis current via the diode and light up the led.........
Good try
Try and error is a way for u to achieve your target.....don't give up , keep learning and try.....I also had try this circuit few year ago........HAHA...
Also , what u mean" no polar LED "?? Do u mean it is "two colur led"???
i only try this on old fashion esc ..........i haven't try this with new band esc...
haha...so i say may be...hehe...
normal one colour led only can light up in one direction.....because it 's also diode....
i know some led can light up in both direction ,but it have two different colour.
Thus ,u find this no polar one should not be led, may be it just a bulb...
