- Circuit design for LEDs on a timer
Hello,
I’m looking for someone who can help me with designing and providing documentation for a project I’m working on.
I’m looking to make something similar to what kids’ light up toothbrushes do. If you think you can provide the design and documentation to accomplish this which I could hand over to a manufacturer to be mass produced, I’d love to talk!
These are the requirements:
Small form factor
Powered by batteries (which can be replaced)
LED light
LED is activated by pressing a small button
LED us on a timer and turns off after 20 seconds
Provide documentation so I can provide to a manufacturer
I’m flexible with the price!
I basically want what’s shown in the attached pictures but with a timer to shut the LED off after 20 seconds.
Thanks in advance.
