A Pico board can however allow better control at lower frequencies within the typical AM radio station (~1000 KHz). While square waves are well-suited for frequency-modulating any PCM audio file (ignoring the unwanted harmonics), they cannot be used well for amplitude modulation. They can only encode ON or OFF instead of different audio amplitudes (think 1-bit envelope). Alright, no emitting arbitrary “.wav” files. We can at least emit a single audio frequency at a time using On-Off Keying. Let’s make some retro game sounds!

If oil manages to make it through the strait, there’s another issue: Following the strikes on Iran, the Yemen-based Houthi military threatened to launch attacks on ships passing through the Red Sea. The Red Sea is a vital trading route between the East and West, sitting between the continents of Africa and Asia. It funnels into the Suez Canal, which leads to the Mediterranean Sea, meaning if ships cannot pass through the Red Sea in the south, where it borders Yemen, boats would instead have to divert around the African continent.
