First I will tell you how it works-
When the Light dependent resistor(LDR) is in Dark the LED turns on but...
When the LDR is in light,the LED turns off.Hence I have made my own dark sensor.
Now,it's your turn to make one.
Lets get started!
Step 1: Order Your Components:
1x100K ohm resistor
1x330 ohm resistor
Some jumper wires or single strand wires.
NOTE: I used 47K ohm resistor instead of 100K resistor cuz I didn't had one. It is better to use a 100K ohm resistor instead of 47K one.
