Unlocking the Circuit: Journey into Schematics

The schematic outlined above is a complete schematic outlining the entire Cactus Kit! 

Component Meanings


Resistors are usually drawn like the image shown above. Engineers will also usually include a name above each resistor—like “R1” and “R2” for resistors 1 and 2. They may also include the value of the resistor above the symbol—like “1 kΩ” for 1 kilohm or 1000 ohms. The symbol “Ω” is the Greek letter omega—it is the symbol used for ohms (ohms are the standard unit used for measuring resistance). This lets others know that the component is a resistor and what its resistance is.

Diodes, such as light emitting diodes (LEDs), are represented in circuit schematics using symbols like the one shown above. Diodes have both an “anode” (positive side) and a “cathode” (negative side). Typically, LED symbols like the one shown here are drawn with two arrows emanating from the diode to represent light leaving the diode. In the symbol shown above, the cathode is shown by the horizontal bar at the bottom tip of the triangular figure which represents the diode. The anode is represented by the flat top side of the triangular figure where there is no horizontal bar. It is important to draw diodes in the correct orientation to indicate how they are placed in circuits because it is necessary for the circuit to function correctly. For example, an LED inserted into a circuit “backwards” will not light up.


Switches are sometimes represented differently in circuits depending on whether the switch is depicted as open (off) or closed (on). The first symbol shown below depicts an open switch and the second symbol depicts the switch in its closed state. Usually, it is enough to depict a switch in either state when drawing a circuit diagram. However, if an engineer wishes to specifically describe a circuit when a switch is closed, they will use the closed switch symbol. If an engineer wishes to specifically describe a circuit when a switch is open, they will use the open switch symbol.
