If EEEGGGG project is approaching!

Hello. There are many ways to create a circuit for detecting light with LDR. However, most simplest form uses an LDR, transistor, relay, and a handful of other components such as resistors, diodes and capacitors.
The site was created for you below, can help. One can, of course, can be optimized, like every other circuit to a desired result.
A list of parts and gives a clear overview. In the figure of 47K "Preset" is a (47K 47,000 ohms) variable resistor that can control the sensitivity of the LDR. Red LED indicates "Power" and "Green" indicates when the relay is activated.
