Schmitt Trigger Inverter Oscillator - Fun with Nand Gates and RC Networks
Taking a look at the difference between a normal and a Schmitt trigger logic gate input with scope traces, and how to calculate the frequency of a Schmitt trigger inverter oscillator based on the charge and discharge time of the resistor-capacitor network.

Putting the oscillator to use to generate odd pulse waveforms to blink LEDs in custom patterns and building up toward a sound effect generator, with future projects in mind.
