Switches The are many types of switches but in this section we'll just go into mechanical switches. Switches allow or stop the flow of current or control which path it is to take. The simplest swi

RelaysRelays are basically switches that are controlled by electricity rather than mechanical input. Inside the relay, the current used to alter the state of the switch is put into a coil. As we now f

Transistors Transistors are semiconductors that control current flow. They have three contacts and a small current at one contact can control a much larger current flowing through the other two conta

How to De-solder You'll need two things: Soldering iron - 15-30 Watt for sensitive jobs, You don't want them too hot or they may damage the components. Device to Remove Solder - Either a

Drawing Circuits When designing circuits it is not practical to draw physical likenesses of the components you wish to use. In place of each component a symbol is use to represent it. For example:
