Electronic Components

These are small electronic components available in the laboratory.  You may use a small number of them to build your own sensors or for other purposes on your robot.  There are some restrictions on their use in the competition rules.

For details of how to use the optical components, see the optical parts web page.  For details on building electronic circuits, making plugs for the Handyboard, etc., see the instructions on building circuits.

Reflective optical sensor, pins		OPB704 component, can be used to build a sensor. See the optical page for details. Manufacturer's data sheet.
Reflective optical sensor, wires		OPB704W component, use to build sensor. See the optical page for details. Manufacturer's data sheet.
LED, yellow, current limited		Yellow light-emitting diode, with built in resistor to limit the current.  It can be connected directly to a Handyboard digital output, for use as a status indicator. See the startup page for details of how to connect and use this LED in the RoboRugby starting sequence.
LED, red		Kingbright L53ID light-emitting diode, can be used to build a sensor, for decorative purposes, etc. See the optical page for details. Manufacturer's data sheet.
LED, infra-red		Temic TSUS5202 light-emitting diode, can be used to build a sensor.  The rules restrict horizontal emission of infra-red light. See the optical page for details. Manufacturer's data sheet.
Light sensor, visible		Texas Instruments TSL250 visible light detector, can be used to build a sensor, using light from a red LED or from room lighting. See the optical page for details. Manufacturer's data sheet.
Light sensor, infra-red		Taos TSL260R infra-red light detector, can be used to build a sensor, using light from an infra-red LED. See the optical page for details. Manufacturer's data sheet.
Strips of pins		Strips of pins on a 2.54mm pitch.  A group of 4 can be used to make a plug to connect a sensor to the Handyboard. See the web page on connecting to the Handyboard for details.
Resistor		Resistors are available in the laboratory, with values from 10 ohm to 1 megohm, with power rating 0.25 W.
Capacitor		Capacitors are available in the laboratory, with values from 10 pF to 1 mF.  Capacitors of 1 uF and higher are polarised, and must be connected the right way around!
