2022-02-08 (Tu) RangerRogue Servo schematic

The Ranger's circuit seemed straightforward, but I will be teaching this and instructing others, so I made a schematic. Another reason was to get an accurate count of the Ground and Voltage terminations I will need. Early on, I foolishly assumed I could run all of my devices right to Arduino pins, but I have five ground pins, and the board has one or two, depending on which I choose. I need four connections to Vcc, and the board only has one of those, or two if I tap off the ISP headers. I'll need a stripboard with plenty of spots for voltage and ground to make this easy. I had to fight with my house's wiring, which foolishly tapped off the bathroom's GFI circuit to feed the outlets in an adjacent room. I spent wood cutting three copies. I lost the first to power loss, the second had incomplete cuts on the interior features, but the third worked.
