Components Required –
� BREADBOARD
A breadboard is a solder less device for temporary prototype with electronics and test circuit designs . Most electronic components in electronic circuits can be interconnected by inserting their leads or terminals into the holes and then making connections through wires where appropriate . The breadboard has strips of metal underneath the board and connect the holes on the top of the board . The metal strips are laid out as shown below . Note that the top and bottom rows of holes are connected horizontally and split in the middle while the remaining holes are connected vertically .
� RESISTORS
A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element . In electronic circuits , resistors are used to reduce current flow , adjust signal levels , to divide voltages , bias active elements , and terminate transmission lines , among other uses . Highpower resistors that can dissipate many watts of electrical power as heat , may be used as part of motor controls , in power distribution systems , or as test loads for generators . Fixed resistors have resistances that only change slightly with temperature , time or operating voltage . Variable resistors can be used to adjust circuit elements ( such as a volume control or a lamp dimmer ), or as sensing devices for heat , light , humidity , force , or chemical activity .
