The frequency of the oscillator can be calculated using the following formula:
You can use these values as a starting point and adjust them to get the desired frequency.
f = 1 / (2 * R1 * C1 * ln(3))
The 74HC14 IC contains six independent Schmitt trigger inverters. A Schmitt trigger is a type of comparator that produces a digital output based on the input voltage. The 74HC14 has a built-in hysteresis, which means that the output changes state only when the input voltage crosses a certain threshold.
The 74HC14 is a popular hex inverter Schmitt trigger IC, and it's commonly used to build simple oscillators. Here's a full story on how to calculate the oscillator frequency using a 74HC14:
To make it easier to calculate the oscillator frequency, you can use an online calculator or create a simple spreadsheet with the following formulas:
