STARTER SOLENOID "Relay" — All cars are wired so that the batterys main cable connects to the starter motor windings "the thick cable is needed for large current flow, right?". This wire must be switched on and off, of course, and it would be costly and inefficient to route it through the ignition switch "not to mention the size of the switchs components required to carry such current!". Consequently, a relay is necessary.

You can also see that I’ve made it very easy for heat to move away from the regulator (U1) and into the ambient environment or into other portions of the PCB. U1’s thermal tab is connected to a large copper pour, and this copper pour is shot through with vias that conduct heat down to the internal ground plane. If I were really worried about thermal issues I could also connect these vias to a copper pour on the bottom side of the board, but in this case, it would have been total overkill.

There are different panelization and de-panelization methods depending on the application of the PCB, thickness, shape, component layout, type of edges, and other factors. The two popular methods are the V-groove panelization and the breakaway tab panelization. Each of these uses a different method to separate the boards from the main array and has its advantages and limitations.

And while a reset may also be externally generated by issuing a command (referred to as a soft reset), to achieve a full reset it is recommended to use the nReset pin (or of course you can also cycle power). On the other hand, if this pin is not to be used then it is recommended that it is either left floating or tied to VDD via a series resistor of value ≥2 kΩ.

RC servos are used to provide actuation for various mechanical systems such as the steering of a car, the control surfaces on a plane, or the rudder of a boat. Due to their affordability, reliability, and simplicity of control by microprocessors, they are often used in small-scale robotics applications. A standard RC receiver (or a microcontroller) sends pulse-width modulation (PWM) signals to the servo. The electronics inside the servo translate the width of the pulse into a position. When the servo is commanded to rotate, the motor is powered until the potentiometer reaches the value corresponding to the commanded position.

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.

The circular arrangement of electromagnets is divided into groups, each group called a phase, and there is an equal number of electromagnets per group. The number of groups is chosen by the designer of the stepper motor. The electromagnets of each group are interleaved with the electromagnets of other groups to form a uniform pattern of arrangement. For example, if the stepper motor has two groups identified as A or B, and ten electromagnets in total, then the grouping pattern would be ABABABABAB.

When implementing a real-time system, we find a circular buffer critical whether we are using a DSP processor or a general purpose processor (GPP). However, with a GPP we may have to implement the circular buffer in software. As discussed in the previous section, with each new sample, we have to update the pointer which contains the address of the newest sample. With a circular buffer implemented in software, the programmer needs to take care of updating the buffer pointers after each read and write operation. When the pointer reaches the end of the buffer, the program must wrap the pointer back to the beginning of the buffer.
