Footnotes For those who must know why the 555 timer in this configuration is designed to keep the capacitor voltage cycling between 1 / 3 of the supply voltage and 2 / 3 of the supply voltage. So when the capacitor is charging from 1 / 3 V CC to its final value of full supply voltage V CC having this charge cycle interrupted at 2 / 3 V CC by the 555 chip constitutes charging to the
