Here’s an easy project that simple enough for electronic beginners, plus the supplies required are probably laying around your house or workshop.
Could you buy the same thing for just a few dollars more? Sure you could, but you’d miss out on the satisfaction of assembling this project all by yourself.
Here’s what you need:
2 high intensity white LEDS (you can use other colors if desired)
small perf board
2 470 ohm resistors
toggle switch or slide switch
9V battery snap
small project box (you can use an Altoid tin)
electrical wire (about 2′ total)
