+\subsection{Resistor Calculator}
+\screenshot{plugins/images/ss-resistor}{Resistor calculator}{img:resistor}
+
+The resistor calculator is a plugin that works in 3 modes:
+
+\subsubsection{Colour to Resistance}
+
+In Colour to Resistance mode, use the menus to select the colours of the
+bands of a resistor which you would like to know the resistance of.
+
+\subsubsection{Resistance to Colour}
+
+In Resistance to Colour mode, use the menus to select the unit that you
+would like to use (choose from Ohms, Kiloohms, Megaohms), and use
+the on-screen keyboard to input the value of the resistor that you would
+like to know the colour code of. The colour codes are presented
+\opt{lcd_color}{graphically and} textually.
+
+\subsubsection{LED resistance}
+
+LED resistance calculator is used to determine the resistor necessary to light
+an LED safely at a given voltage. First, select the voltage that the LED will
+use (the first option is the most common and a safe bet), and the current
+that it will draw (likewise with the first option). Then, use the onscreen
+keyboard to type in the supply voltage and, if selected, the custom
+foreward current. This function produces safe estimates, but use your own
+judgement when using these output values. Power rating and displayed resistance
+are rounded up to the nearest common value.
