Introduction: Heart Night Light

Picture of Heart Night Light

I found broken heart night light that used bulb. I removed everting else but body. After that I played with LDR. Finally I get it work as I wanted.
I used:
- 3 x Ultra bright red leds
- 2 x NPN transistors (2N3904)
- 1 x 100K potentiometer
- 1 x LDR
- 1 x 1K resistor
- 9V battery
- Hot glue

I soldered parts together. Hot glued leds together. Put circuit inside to heart lamp body. Only LDR is outside. Now my sisters doesn't need to turn it on, because circuit make it automatically.
