Hi All,
I would like to integrate a work light on my powered screwdriver.
I have added to LED (3mm) bulbs to my tiny cute IKEA screwdriver on two sides of the body of the screwdriver towards the tip. The battery powering the tool is one 3.7v 16850.
The wiring I did was simple, (maybe wrong?)
Just wire the LEDs to the motor terminals in forward and reverse polarity, so they start to light up as the motor gets the forward/reverse polarity power switching.
However, the problem is only one of the LEDs is surviving after a few minutes of use. That dying/dimming LED is mostly forward driving one ( I tried replacing the LEDs 3 times). Is there any back emf or something acting here?
How do I implement this successfully, please?
Kind Regards
