Dual LED Flasher Uing 555 Timer IC.

                    DUAL-LED FLASHER USING 555 TIMER IC.

Components needed:

1. 555 Timer IC

2. Resistors: R1 (1K Ohm), R2 (100K Ohm), R3 (330 Ohm), R4(330 Ohm)

3. Capacitor: C1 (100nF)

4. 2 X LEDs: 

5. Power supply: Vcc (5V) or Battery 9V

6. Miscellaneous: Breadboard, connecting wires.

Circuit connections:

Steps:

1. Connect Vcc (5V) to the positive rail of the breadboard.

2. Connect GND (ground) to the negative rail of the breadboard.

3. Place the 555 timer IC on the breadboard.

4. Connect pin 1 (GND) of the 555 timer IC to the negative rail.

5. Connect pin 8 (Vcc) of the 555 timer IC to the positive rail.

6. Connect pin 4 (Reset) of the 555 timer IC to the positive rail.

7. Connect pin 2 (Trigger) of the 555 timer IC to the capacitor using a 1K Ohm resistor (R2).

8. Connect pin 6 (Threshold) of the 555 timer IC to the capacitor along with a 1K Ohm resistor (R2).

9. Connect pin 3 (Output) of the 555 timer IC to (-ve)  of the Red LED (LED1) along with a 330 Ohm resistor (R3).

10. Connect pin 3 (Output) of the 555 timer IC to (+ve) of the Green LED (LED2) using a 330 Ohm resistor (R4).

11. Connect (-ve) of the Green LED (LED2) to the negative rail.

12. Connect pin 7 (Discharge) to the positive rail along with a resistor(R1).

Result:

Once you have constructed this circuit, the LEDs (LED1 and LED2) will alternately flash, creating a dual LED flasher effect. The timing of the flashing can be adjusted by changing the values of resistors (R1, R2, R3) and capacitor (C1) in the circuit.

Please note that it's important to exercise caution when working with electrical circuits, and ensure you have the necessary knowledge and safety precautions in place.
