Electronic schematics are the detailed diagrams of the components and connections required to create a specific electronic process. These are specific symbols and layouts used to indicate the type of circuit or connection required. A detailed explanation of the intended purpose of the circuit is usually provided.

Instructions

Difficulty: Moderate

Step1

Get a schematic drawing of a circuit that you want to create. This could be anything from a simple power touch switch to a fully functional robot, complete with a remote control. All these devices are powered and programmed by electronic circuits. You can find free schematics online (see Resources below).

Step2

Compile the required circuit board, wires, connectors and pins needed to complete the project. You can identify the parts needed by looking at the schematic for a detailed explanation of what is required. Beside each pin, there is an alpha numeric code that corresponds to a standard pin or part. The image on the top right hand side gives you the overall dimensions of the finished product, so you can determine the size circuit board and if any casing is required.

Step3

Purchase or turn on your soldering iron and make sure that you have enough Rosin Coil solder wire for the project. Each pin and connection to the circuit board needs to be soldered into place.

Step4

Intersect wires to create a simple conductor anywhere 2 lines meet at a perpendicular angle. Connections that pass over or under are shown without a dot. Resistor devices do not carry the flow of the electronic charge and are shown with a series of spikes in the line. Power connections provide the voltage as a notation, and the ground line appears as an intersection with parallel lines below in the shape of a triangle. Use these standard symbols to read the schematic and build the circuit.
