Good morning everybody!
I am newbie and just started learning about electronics and soldering.
I would be greatly appreciated if some one knowledgeable can help me identify electronic part I need for my project.
It supposed to be a 15Hz pulse or frequency generator (I am not sure). It has blue LED that reflects frequency pulsation rhythm.
This part is tiny and powered by 9V battery.
I have attached picture of this part for your reference.
