BROUHAHA

On startup, the module randomly selects 4 waveforms from the bank and assigns them to the outputs. Each time you power cycle or restart the module, you'll get a different combination of waveforms. Quick limiting inspiration.

Waveforms

The module contains a bank of 8 different waveforms:

1. Sine Wave - Classic sine wave oscillating between 0-1V
2. Square Wave (25% Duty) - Square wave with a 25% duty cycle
3. Triangle Wave - Standard triangle wave ramping up and down
4. Pulsing Pattern - Complex wave combining slow and fast sine modulation
5. Random Noise - White noise generator
6. Inverted Triangle - Upside-down triangle wave
7. Morse SOS - Repeating SOS pattern in Morse code (...---...)
8. Triple Pulse - Three evenly-spaced pulses per cycle

Technical Details
