Arduino-Controlled Rotary Telephone (DIY Escape Room Prop Tutorial)

In this video, I'm going to revisit and redesign an idea from a tutorial I made a few years back - the rotary phone escape room prop. I didn't realise it then, but my last project ended up being quite specific to handsets on the UK telephone network (with assumptions about particular timing patterns, wiring etc.), and so ended up being not as portable as I hoped - apologies to anyone who had difficulties following along from other countries! So, for this project, I'm taking a completely different approach - wiring an Arduino (or ESP8266 / ESP32 or any similar microprocessor) directly to the mechanical components of an original 1970s phone - the rotary dial, the hook switch, the solenoid that rings the bells, and the microphone and earpiece speaker. This should be completely portable between handsets, whatever public telephone network they were designed to be used on. Then, using a DFPlayer Mini MP3 module to handle the audio output, I'll show you how to program completely custom behaviour of the telephone as a Finite State Machine (FSM): you can trigger incoming calls (manually, via a switch in the control room or from control software such as Node-RED/M3/ERM) that makes the telephone ring and, when answered, delivers a specific message to players. Or you could have players dial an outgoing call to any one of thousands of different numbers, of any length, each one mapped to a unique MP3/WAV audio file on the SD card inserted into the DFPlayer. And, you can have the behaviour of those numbers change dynamically during play - to play different messages, or for certain numbers to be engaged or unobtainable at different points in the game, for example. This provides many different opportunities to integrate into an escape room game prop. Since the entire behaviour is running on an Arduino, it's also easy to program in the ability to control any other external hardware - to release a maglock or power any other device via a relay etc. I believe this makes this the most flexible and feature-rich rotary telephone prop tutorial available.
