POLICE LIGHT CIRCUIT

This is the mot simple way for implementing the police light circuit. The main components are listed below.

• NE555 Timer IC (2 Nos)
  
   
• LED (Red and Blue)
  

• 12V Power Supply
  
• Resistors(Values as shown in circuit diagram)
• Capacitors(Values as shown in circuit diagram)
• Breadboard or PCB

WORKIG

           

           Both 555 ICs are cascaded which works as astble multivibrators, each of them with a different freqency. Their otputs are connected to two groups of LEDs. The frequency and nature of flashing can be adjusted by changing the values of R and C as mentioned in the previous circuits. You can change the number of LEDs, but it is necessary to adjust the value of R1 not exceeded the maximum current of LEDs.
