It is a circuit that uses 555 Timer IC and configures it into Astable mode, with added Pot to wary its duty cycle for PWM, timing, Dimming LED, Speed Controlling DC motor, and many more uses.

It can be operated by 5V to 12V DC.

Component:

NO | Name | Value

-------|--------------------------|--------------------

2 | Terminals | 2 PIN

2 | Resistor | 1K Ohms

1 | Potentiometer | 5K Ohms

1 | DIP 8 IC Base | (8 PIN Base)

1 | 555 Timer IC | DIP 8

1 | Capacitor | 10 uF

1 | LED | Any Color

How To:

1 | Solder Both 1K resistors in the position of R1 and R2.

2 | Then Solder Capacitor is in the Position of C1 (you can change the value as it changes the timing).

3 | You can take any value Potentiometer for RP1 and then solder it on the position.

4 | In place of U2 insert 555 Timer IC, keep the placement in mind. And it's good to solder the IC Base instead of the IC itself.

5 | J1 and J2 are terminals.

5 | Insert the LED in its position.
