so im using a lm555 ic timer to make a oscillator for a 40khz ultrasonic sensor for those of you thats not familiar with this here is a data sheet of it
https://www.electro-tech-online.com/custompdfs/2009/09/ZL3555.pdf
i wanna address the equation where it says f = 1/T = 1.44/((Ra + 2Rb)C)
well its not really that equation but does anyone know whats the best capacitor to use with the lm55 in creating the oscillator?
