Use a wire stripper to remove about 1/8in. (3 mm) of insulation from the end of the wire. Lay the bare strands in the inner section of the connector. Use crimping pliers to tighten the two small tongues firmly around the insulated part of the wire. On the other side of the connector, push the wire strands back and down flat. Hold the connector blade upwards to avoid solder running into the spade part.

Let the connector cool before sliding the cover back. Fitting a bullet connector. Remove insulation with a wire stripper. Use a wire stripper to remove about 3/8 in. (10 mm) of insulation from the end of the wire.

Such solenoids operate in three stages, the disengaged, partially engaged and engaged. In the disengaged position the drive gear is released and no current is flowing. In the partially engaged stage, current from the starter switch flows through both the pull-in and the hold-in coils.

Before you disconnect anything, make absolutely sure you know how to put it back. Number both sides of each connection with labels made of masking tape. If necessary, make drawings of cable routes and how clips fit. Use a craft knife or razor blade to cut away the wrapping from the damaged section. Take care not to cut into the plastic cable insulation.

Although this device uses an I2C interface with communication speeds up to 1 MHz, two of the eight pins are dedicated to Alert (pin3) and nReset (pin 6). The Alert pin is intended to be connected, if desired, to an interrupt pin on a microcontroller. According to section 3.5 (ALERT Pin) of the datasheet, "The output of the pin depends on the value of the temperature reading relative to programmable limits," and its function is "explained in a separate application note.

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.

This wire is flexible enough to be used on straights, curves and hills. The vehicles are fitted with a motorised chassis and rechargeable battery which pushes the vehicle forwards via a small motor and gear arrangement, following the guide wire. The magnet offset to one side on the chassis is what activates the various additional modules (more on those later).

They are not designed to spin continuously. Used to position print heads in ink jet printers, plotters, scanners. Travel at set speeds. Go to a spot and stop. When stopped and still turned on, will attempt to hold it is position. Forcing it to move in this position can damage the motor. Typically is controlled by a circuit board that counts shadows with an LED and light sensor or has a resistor that changes value depending upon position. Often zooms to one side when powered on to figure out where it is at.

The stepper motor is known by its property to convert a train of input pulses (typically square wave pulses) into a precisely defined increment in the shaft position. Each pulse moves the shaft through a fixed angle. Stepper motors effectively have multiple "toothed" electromagnets arranged around a central gear-shaped piece of iron. The electromagnets are energized by an external driver circuit or a micro controller. To make the motor shaft turn, first, one electromagnet is given power, which magnetically attracts the gear teeth. When the gear teeth are aligned to the first electromagnet, they are slightly offset from the next electromagnet.

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.
