Flashlights Finder Circuit using LM3909 Oscillator
Flashlights Finder Circuit using LM3909 Oscillator - What follows below is the schematic of Flashlight Finder circuit diagram using the LM3909, a monolithic oscillator designed to flash Light Emitting Diodes (LEDs).
As seen in the above circuit: the LM3909, capacitor, and LED are installed in a white translucent cap on the flashlight’s back end. For flasher power, a contact strip is needed in addition to the case connection.
