The sharp edge of the hole will soon chafe through wire insulation and cause a short circuit. Whenever you pull a connection apart, look for corrosion which might cause bad contact. If necessary, clean contacting metal surfaces with a fine file or emery cloth.

A servomotor is a specific type of motor that is combined with a rotary encoder or a potentiometer to form a servomechanism. This assembly may in turn form part of another servomechanism. A potentiometer provides a simple analog signal to indicate position, while an encoder provides position and usually speed feedback, which by the use of a PID controller allow more precise control of position and thus faster achievement of a stable position (for a given motor power). Potentiometers are subject to drift when the temperature changes whereas encoders are more stable and accurate.

As the motor rotor turns, a sinusoidal voltage is generated proportional to the speed (step rate). This AC voltage is subtracted from the voltage waveform available to induce a change in the current.

Care should be taken when depaneling the perforated-tab PCB array; otherwise, an incorrect method will splinter or tear the solder-mask or active surface layer. The ideal breakout method should not cause any damage to the board or transfer stress from the PCB surface to the components.

As you may have noticed, this is one of those annoying situations in which the pin configuration is the opposite of what you want: the DAC’s input pins move from bit 7 to bit 0 going downward, whereas the MCU’s output pins move from bit 7 to bit 0 going upward. I couldn’t remedy this by re-assigning the microcontroller pins because I wanted the data bits to correspond to the actual bits of the Port 2 register (so that I could write a full byte to the DAC without moving bits around). So I ended up with some awkward routing, but nothing terrible.

Some have two wires traveling to the circuit board much like between a DC motor and ESC. Attached to the board are wires for motor power and again three wires going to the arduino, the same three wires mentioned above.

Before cutting out damaged wires, make sure that the colour coding is the same at each end of the damaged section of each wire, and that it is not so discoloured that it is unrecognisable. If there is any chance of confusion, label both ends.
