Part 4/9:

The Circuit Board Connection

Central to its functioning is a circuit board responsible for controlling the necessary timing for the toasting process. Unlike older models that operated on simple mechanical components, modern toasters utilize integrated circuits to determine how long the bread should be toasted based on user settings. These settings can be misleadingly referred to as merely “six options” on the darkness dial, yet due to their variable control, these dials can effectively create hundreds of toasting variations.
