Protoboard | 
A thin plastic board full of holes used to hold components that are wired together. It is commonly used for prototyping and experimenting with circuit designs. |  | 
| 
Resistences | 
A measurement of the difficulty encountered by a power source in forcing electric current through an electrical circuit, and hence the amount of power dissipated in the circuit. Resistance is measured in ohms. |  | 
| 
Circuit | 
A configuration of electrically or electro magnetically connected components or devices. |  | 
| 
Capacitor | 
A device used in electrical circuits . The capacitor stores an electrical charge for a short period of time, and then returns it to the circuit. Common types of capacitors include tantalum, electrolytic, ceramic, and film capacitors. |  | 
| 
Microcontroller | 
Known as an MCU, a microcontroller is a type of microprocessor that can contain an entire "computer on a chip". |  | 
| 
Multimeter | 
 An instrument that measures electrical quantities such as voltage, resistance and amperage. |  | 
| 
Photovoltaic Cells | 
Formerly used exclusively in space, photovoltaic cells convert sunlight into electricity. Photo=Light; Voltaic=Electricity |  | 
| 
Relay | 
A device that responds to a small current or voltage change by activating switches or other devices in an electric circuit. |  | 
| 
Sensor | 
A sensor is a type of transducer. Since a significant change involves an exchange of energy, sensors can be classified according to the type of energy transfer that they detect. |  | 
| 
Led | 
 |  | 
| 
Single pole switch | 
A switch with one input wire. |  | 
| 
Solar cell | 
 A semiconductor device that converts the sunlight into electric energy. Also referred to as a photovoltaic cell. |  | 
| 
Paralel port | 
A cable used to transmit information from a device to another. |  | 
| 
Screws | 
Little metal pieces that are used to attach |  | 
| 
Switch | 
A type of interruptor. |  | 
| 
UTP Cable | 
A bound or sheathed group of mutually insulated conductors. | 
 | 
| 
Motors | 
The main engine |  | 
| 
Soldering Iron | 
The tool used to melt and apply solder. | 
 | 
| 
Alligator Clips | 
Used to temporarily hold an electrical connection together for testing or soldering. Often made of nickel plated steel. Can be found with vinyl insulators. |  | 
| 
Jumper wires | 
Cables to conect in the protoboard. |  | 
| 
Electric tape | 
To protect the cables |  | 
| 
Cable ties | 
To attach all the cables in their place. |  | 
| 
Light sensor | 
Used to detect when the light is on or off. |  | 
| 
computer | 
To control all the system. |  |
