Introduction: Your First Electronic Pcb/project

About: I am jwoo2023

Hehe... Your project is here.
A LED activator.
Simple...

Step 1: Needs...

PCB(above)
LED(small)
510ohm resistor
3v flat button cell battery
Thin wire

Step 2: In Goes the Pieces...

Print the pcb layout on to paper.
Push the LED in to the pcb where it's marked.(Flat/short side of led is -)
Push the resistor in.
Solder or glue the thin wire on to each side of the battery.
Push the + through the hole and - through the hole at the bottom.
connect the resistor(one side) to the led +.
connect the - of the led to the - of battery.
connect the + of the battery to the resistor(other side).
Done!

Step 3: Light!

    can u plz tel me why particularly u selected a 510ohm resistor only...and also tel me why particularly u selected 3v flat button battery only and also help me with how to select resistors and batteries for any different simple projects

    I used a 510 ohm resistor only because it will make the led light up at the brightest, also I didn't use a 3v button battery, i used a 9v. I used the 3v button battery because it's compact, and you dont need a resistor when you use a 3v button cell battery.

    i made one of these as a fish lure once. believe it or not it works under water.
    i didn't have to glue the electrode wire or solder them onto the cell.i used a little pressure from the plastic case i used. have fun....

    The flasher LED attracted fish. Catching the fish required knowledge of bait and lures. I am working on another attractor- a buzzer. It is a miniature relay connected as a buzzer. Hope it works.
