The laser used for the transmission angle of the mirror should be set well above should be fixed and is 30cm from the ground. Mirrors, Laser, Ldr should be fixed and should sway camouflage Mirrors whether cables will yield more if stored.
NOTE: 1 (when pressing the RESET button to silence the siren must have light on LDR s)
2nd half while adjusting the angles of the mirrors with LED 1 and LED 2 can be benefited from. )
Our environment is used as the light source laser light source as is known, they operate at low voltage of 12v circuits we feed our 9 to the end of the laser must be connected to the 220 ohm 1W resistor. That will reduce the resistance heating of 1W.

8051 Programmable Power Supply
Circuit Operation: Circuit diagram appears in the 0-5 the entered value from the keypad circuit, which is connected to port P1 applied to the integrated DAC 0808 DAC output is obtained from the analog voltage. P0 port is connected to the 7-segment display of the absolute value of the voltage, which is connected to port P2 indicator shows the decimal value of the voltage. On the keypad “*” key to delete the entered value, “#” key, the entered value is used to convert the analog voltage. Output of 0-5 V 0.1 V-0, 2Volt precision analog voltage is obtained.
