C1) to stabilize the operation of the timer circuit. This capacitor is typically referred to as the "timing capacitor" and is used in conjunction with the resistors connected to pins 6 and 7 to set the timing interval of the 555 timer.
When the control terminal is connected to ground through a capacitor, it helps to maintain a stable voltage at this pin. This is important because any fluctuations in voltage at the control terminal can affect the timing accuracy of the timer circuit.
Additionally, the capacitor at the control terminal helps to filter out any noise or unwanted signals that may be present in the circuit. It acts as a low-pass filter, allowing only the desired signals to pass through and blocking any high-frequency noise.
Overall, the capacitor connected to the control terminal of the 555 timer IC helps to stabilize the operation of the timer circuit and ensure accurate timing intervals.

Control pin of 555 Timer:
The control pin on the 555 timers is normally connected to the ground through a capacitor (∼ 0.01μF because the noise from the supply line can ride through this simple divider adding small capacitor filters out high-frequency noise that can cause the comparison point to vary slightly

- Pin 5 of 555 Timer is the control pin.
- This makes the oscillator cycle more consistent.
- This pin can also be used to change the internal voltage reference to allow modifying the oscillator frequency or duty cycle.
IC 555 has three operating modes namely:
- Bistable mode or Schmitt Trigger
- Monostable Mode: In this mode, the 555 functions as a pulse generator.
- Astable(Free running) Mode: In this mode, the 555 operates as an oscillator.
