Spread out the cuts across a bundle of several wires: if many joins are opposite each other their bulk may make it difficult to fit the loom into the car. If possible, replace wiring with new wire of the same colour. The new wire must be the right size: there are five sizes, depending on current rating. Repairs in wrapped sections of the loom are the only places where you may join wires by twisting them together and soldering the joint mainly because there may not be room for any other method.

Most computer controlled DC motors are pulsed. Pulses of a fixed voltage are sent to the motor, usually by an Electronic Speed Controller or ESC. A pulse of 1.5 ms causes no motion. Wider pulses cause faster spinning in one direction. Shorter pulses cause faster spinning in the opposite direction. Eventually, an overstressed ESC stops pulsing and turns one wire on and one wire off, depending on the direction.

Torque curves may be extended to greater speeds if the stator poles can be reversed more quickly, the limiting factor being a combination of the winding inductance. To overcome the inductance and switch the windings quickly, one must increase the drive voltage. This leads further to the necessity of limiting the current that these high voltages may otherwise induce.

The ease of loading and unloading the PCBs, as well as the ability to handle multiple PCBs, are important in high production lines. In addition, fixtures should provide thermal protection to the heat sensitive areas of the PCB.

Rubber grommets are used where wirespass through holes drilled in the bodywork,to prevent sharp edges cutting theinsulation. Cable clips The loom and individual cables areheld to the bodywork by various types of clips.

They have to be connected to the arduino through a motor shield or custom built circuit. They are typically the most expensive. Stepper motors can have 4, 5, 6, or 8 wires. To use them with the arduino, understanding the internal wiring is absolutely necessary. The best way to learn the internal wiring is to assume no manual exists, and "discover" the internal wiring.

The datasheet goes on to say that "the nRESET pin is internally connected to VDD with a pull up resistor of 50 kΩ." So... why are there two options for how to configure the nReset pin when it is not being used? Why not just recommend that it should be left floating (since it is already pulled high internally)? And, if there are indeed technical reasons for when the pin should be externally pulled up to VDD (for better noise immunity, as an example) then let us know what those technical reasons are.

This means that when the next electromagnet is turned on and the first is turned off, the gear rotates slightly to align with the next one. From there the process is repeated. Each of those rotations is called a "step", with an integer number of steps making a full rotation. In that way, the motor can be turned by a precise angle.
