Stick-on labels are provided in strips to identify the components on the project box.
Template for box lid
A paper template is provided in order to obtain the correct placement of holes for the components.
9-V battery holder
9-V battery clips in to this laydown container. The supplied hook and loop strips are used to stick the holder down to the inside of the project box.
red wire is positive; black is negative
Pushbutton, momentary, normally open
Used a test button for the delay unit
Panel jack for AC/DC adapter
Receptacle for 9-V AC/DC adapter as an alternate power source
When the AC/DC adapter is not plugged into the jack, terminals 1 and 2 are shorted internally. This connection opens when the adapter is plugged in. Because of this feature, terminals 2 and 3 are used to supply power from the adapter, while terminals 1 and 2 are used to supply power from the battery. Terminal 2 is shared by the two power sources and is connected to ground.
3.5mm mono panel jack
One of these is used as a receptacle for the microphone cord; the other is used as an input jack for triggers other than the on-board sound and photogate triggers. Examples include a contact trigger and a light-activated trigger.
When a plug is not inserted into the jack, terminals 2 and 3 are shorted internally. This connection opens when a plug is inserted. Terminals 2 and 3 are used to connect the sound trigger and photogate to the delay unit internally. Terminals 1 and 3 are used to connect an external trigger to the delay unit.
3.5mm stereo panel jack
One of these is used as a receptacle for the photogate cord and the other two are used for the output jacks.
Terminals 1-3 connect to the sleeve, ring, and tip respectively of the corresponding stereo plug.
Used to mount LEDs on the project box.
Used to hold the PCB away from the lid components
4-40 bolts, 1/4" long
Used to mount the PCB to the lid and the standoffs

Polarity and Connections
3.5mm mono connector (male)
This is the plug for the microphone cable.
The sleeve is connected to ground and the tip to the microphone input.
3.5mm stereo connector (male)
This is the plug for the photogate cord. One is for the interrupter-style photogate and the other for the individual emitter and detector style.
The tip is connected to +9 V, the ring to the photogate input, and the sleeve to a 470-ohm dropping resistor that then goes to ground on the breadboard.
Used for the microphone cable
Used for the two photogate cables
Hook up wire
Used to make connections between the PCB and the project box lid. (1.5 ft of the yellow wire is used for the photogate cable with individual emitter and detector.)
3 in each
The red and black wires inside the gray sheath (see to right) are used to make extensions for the battery holder wires.
Stick-on number labels
Numbers from 1 - 15 and 17-21 used to temporarily identify the jumper wires to solder from the lid to the PCB
3/32" heat-shrink tubing
Used in wiring the microphone cable, the photogate cable for individual emitter and detector, and extensions for the battery holder wires
