PIR Motion sensor+LDR+Relay, Without Arduino UNO

This small project will add blue light into the water fontain. When dark in the room (adjust LDR by POT) and movement in the room (Adjust sensibility by POT on PIR) the 4 blue LED's will turn on for 20sec (Adjust time by POT on PIR) No need for Arduino UNO or code ! The power source is a 9V battery. The Volt Regulator 7805 brings the 9V to 5V. The wiring is in two parts where I use 5V from Volt Regulator for the components and 9V from the battery trough relay and resistors for the four blue LED's. If you want you can change the LED's for a bulb 230V. In that case the wiring between, power source, relay and bulb is a bit different ofcourse.
