 # Introduction
 
 If you want to build something using a Raspberry Pi, you'll probably use _resistors_.
-Like the previous [`Resistor Color Duo`][resistor-color-duo-exercise] and [`Resistor Color Trio`][resistor-color-trio-exercie] exercises, you will be translating resistor color bands to human-readable labels.

 - Each resistor has a resistance value.
 - Resistors are small - so small in fact that if you printed the resistance value on them, it would be hard to read.
