- 1. RANDOM RUNNING LIGHTS SUBMITTED TO:Er. AMULYA KUMAR PANDA(H.O.D, E&TC) SUBMITTED BY:SMRUTI RANI PATRO 6TH SEM, E&TC F1001203058
- 2. CONTENTS Introduction Block diagram Circuit diagram Component Layout Transformer Rectifier Resistors Capacitors LED 556 Dual timer IC Switch LED arrangement Front panel of the project Conclusion
- 3. INTRODUCTION Many types of lamps are used for turn signal, brake lamps, side and clearance marker lamps, and interior lamps. The simple, inexpensive but reliable electronic device may find numerous application such as warning indicators, exit door indicator in an auditorium, house number flasher, seat number indicator etc.
- 6. components Following are the different components used in this project. 1. 2. 3. 4. 5. 6. 7. 8. Transformer Rectifier Resistors Capacitors LED NE 556 IC ON-OFF switch Connecting Wires
- 7. components Transformer It is a static electromagnetic device which transfers electrical energy(power) from one magnetic circuit to another magnetic circuit keeping frequency constant.
- 8. components Rectifier • • converts AC to DC. Here bridge rectifier is used.
- 9. components Resistors 1. A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. Capacitors A capacitor (originally known as condenser) is a passive twoterminal electrical component used to store energy in an electric field.
- 10. components LED A light-emitting diode (LED) is a semiconductor light source. LEDs are used as indicator lamps in many devices and are increasingly used for other lighting.
- 11. components Switch • In electrical engineering, a switch is an electrical component that can break an electrical circuit, interrupting the current or diverting it from one conductor to another. 556 Dual timer IC • It is dual version of 555 timer IC. So it can be called as dual timer IC. • It can be substituted by NE 566 F, NE 566 N, LM 556, MC 3456, SE 556, TDB 0556.The dual timer 556 can be used with a supply voltage (Vs) in the range 4.5 to 15V (18V absolute maximum).
