The 555 timers linked to the function in the astable feature as a free-running relaxation oscillator can be seen in the below figure. Note that the threshold input is linked with the trigger input. The exterior elements R1, R2, and Cext make the timing circuitry which adjusts the frequency of oscillation. The capacitor having a capacitance of 0 ...

In my first Instructable about the 555 timer chip (Introduction to the 555 timer) I demonstrated a 555 in an astable oscillator. I would like to thank Mike63 for sending me a couple of useful formulas to calculate the frequency and the low time. Frequency = 1 / (0.693 X C1 X (R1 + 2 X R2)) Low Time = 0.693 X C1 X R2

The simplest 555 oscillator takes output pin 3 to capacitor C1 via resistor R1. When the circuit is turned on, C1 is uncharged and output pin 3 is HIGH. C1 charges via R1 and when Pin 6 detects 2/3 rail voltage, output pin 3 goes LOW. R1 now discharges capacitor C1 and when pin 2 detects 1/3 rail voltage, output pin 3 goes HIGH to repeat the cycle:

The figure above shows how a variable mark space ratio facility can be added to any basic IC 555 astable oscillator circuit through a couple diodes and a potentiometer. The feature allows the user to get any desired PWM or adjustable ON OFF periods for the oscillations at the output pin 3 of the IC.
How to make Audio Amplifier Circuit Using 555 Timer
