The Full Story

How to Read Schematics

In this website, schematics are presented in an Excel sheet format. The pink highlighted cells indicate that the wire (one end of the wire) should be plugged into the Redboard while the plain cells are wires that have one or both ends attached to the breadboard.

Key

No Highlight = Pin on the Breadboard

​

Pink Highlight = Pin on the RedBoard

Notation

The breadboard is organized with letters across the x axis and numbers down the y axis. So, J4, for example is pinned across to J and down 4 holes. 

Some things are written with a slash, this just means that the piece you are using has multiple pegs to be plugged into the board. Whether or not there is a specific order to this will be noted on the schematic. 

Schematic Sheet

Each code included on this website will have a handmade "Schematic Sheet to idicate where each wire and piece of equipment goes on the BreadBoard and the RedBoard.

About Side Rails

5v, 3.3v & gnd(-) are special cases. If it is highlighted in pink, then it goes into the RedBoard. If it is not highlighted, then it is most likely going to be connected to one of the strips running along the side of the breadboard. This strip should be connected to the RedBoard somewhere else in order to string voltage through that whole column (this makes sense when looking at the breadboard diagram because the metal is strung from the very top to the very bottom on either side of the board) or string the ground through the whole column.

Pay attention to which side rail (left or right) is being connected to the RedBoard. For projects it is best to stick to one rail or use both rails (assuming they are both connected to power/ground. 

Example

Examine this schematic in comparison to the pictures to see how the color of the wire corresponds to its designation on the sheet.
