STRIPBOARD

10:10 PM  Sabarish  No comments

Stripboard circuit (copper tracks side) Stripboard has parallel strips of copper track on one side. The tracks are 0.1" (2.54mm) apart and there are holes every 0.1" (2.54mm). Stripboard is used to make up permanent, soldered circuits. It is ideal for small circuits with one or two ICs (chips) but with the large number of holes it is very easy to connect a component in the wrong place. For large, complex circuits it is usually best to use a...

Introduction to logic gates:Logic gates process signals which represent true or false. Normally the positive supply voltage +Vs represents true and 0V represents false. Other terms which are used for the true and false states are shown in the table on the right. It is best to be familiar with them all. The different types of gates are as follows:-NOT GATELogic states True False 10 HighLow +Vs0V OnOffAND GATENAND GATEOR GATENOR GATEEX-OR GATEEX-NOR...

Electronics is the study and use of electrical that operate by controlling the flow of electrons or other electrically charged particles in devices such as thermionic valves. and semiconductors. The pure study of such devices is considered as a branch of physics, while the design and construction electronic circuits to solve practical problems is called electronic engineering.
