Square wave generator and capacitance meter with IC 555

Hello, today I will explain how to make two simple circuits with the integrated 555.

SQUARE WAVE GENERATOR

To make a square wave generator we only need a couple of resistors, a capacitor of 0.01µF and another capacitor wich value we will to determine according to the characteristics that we want to our circuit have, to do it we have to apply the following formula.
