Dithering the stepper signal at a higher frequency than the motor can respond to will reduce this "static friction" effect. Because windings are better utilized, they are more powerful than a unipolar motor of the same weight. This is due to the physical space occupied by the windings.

The pulses have a different meaning. The pulses describe a spot to go to. Within the servo there is a feedback mechanism that counts shadows or turns a variable resistor. The servo circuit board then moves the servo to that spot. It knows when it has reached the spot when a certain number of shadows have past or when the resistance reaches a certain value. The arduino has to keep sending the same position over and over again to hold the motor in a current spot. Short pulses go one direction, long pulses the opposite direction, medium pulse widths go to the middle. Middle is typically 1.5 milli seconds.

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.

This allows them to easily fit the boards in the standard assembly, reflow, or automatic inspection machines. In addition to handling the irregular boards, the technologies enable the simultaneous processing of multiple boards as opposed to working on each board individually, hence reducing the production time and costs.

The tab-route or breakaway tab method is suitable for PCBs with either similar or different designs, or where it is not possible or practical to use the V-grooves. The designer leaves a perforated tabs routing space between the different or similar boards, hence allowing for separation after processing.

"Scotchlok" connector The "Scotchlok" connector splices two wires together, using asharp metal blade which pierces theinsulation. This is clamped using a pair ofpliers, and covered with a plastic clip.

The datasheet states (see image below) that this IC—specifically the CMOSens® technology that it uses—is "designed for mass production." Umm, should not this go without saying? I have seen datasheets state "not recommended for new designs," but I do not ever recall seeing one that specifies that the IC, or its underlying technology, is designed for mass production. This benefit makes me question if Sensirion has other ICs that are in fact not designed for mass production. It is all a bit puzzling. Have you seen other IC datasheets call this out? If so, please let us know.

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.
