Figure 1: This relay routing system was used to assign different audio sources to speakers around (or on top of) the dome. The switches in the middle were manual overrides. Today, digital planetarium systems make it easy to drop soundtracks, sound effects, and just about anything else onto a timeline so that the timing and visuals are always in sync.
How to Use 5V Relays With the Raspberry Pi - Circuit Basics

In the previous steps, we already connected the signal pin of the 5V relay to pin GPIO17 on the Raspberry Pi. Here, we use the LED library because it is an easy way to control the digital pins of the Raspberry Pi. We use the line if (p.read_temp_c(3950,1000) > 30) to set a threshold of 30 o C. If the temperature exceeds that threshold, the relay.on function will turn …
