WMS

The Washing Machine Simulator (WMS) incorporates a series of input and output devices which together simulate the actions of a typical domestic washing machine.
A seven segment display may be controlled by four digital outputs to highlight the ‘was program status’. Control is possible by inputs through the coloured push buttons and indicated by colour LED’s. Two outputs are used to control the disc motor, one turns it on and the other alters the direction of rotation. Motor speed may be varied through pulse width modulation. Speed is measured using a sensor through the four holes in the disc that represent the washing machine drum. Test points are fitted and fault switch for teaching diagnostics.
