Night Light With Ldr
with ldr
Things Needed
1. Transistor (2N3906)
2. leds
3.resistor (brown-black-orange-gold)
4.LDR
5. Another resistor for saving the led from burning out(red-red-brown-gold)
6.some hookup wires for connecting
the parts together
7. Breadboard

Step 1
connect one leg of the (brown-black-orange-gold) resistor to negetive and another to the ldr
Step 2
connect a wire from the place where the (brown-black-orange-gold)resistor and the ldr is connected , to the middle leg of the transistor
Step 3
connect the left leg of the tansistor to negetive
Step 4
connect the right leg of the transistor to one leg of the led and the other leg of the led to be connected with the (red-red-brown-gold) resistor and the resistor should be connected to positive
Done
this should look like this
