Washing Machine

A washing machine (laundry machine, clothes washer, or washer) is a machine designed to wash laundry, such as clothing, towels, and sheets. In the early 1990s, up market machines incorporated microcontrollers for the timing process. These proved reliable and cost-effective, so many cheaper machines now incorporate microcontrollers rather than electromechanical timers.

Features available in most modern consumer washing machines:
1. Predefined programs for different laundry types
2. Variable temperatures, including cold wash
3. Rotation speed settings
4. Delayed execution: a timer to delay the start of the laundry cycle
5. Child lock
6. Time remaining
