The paper deals with the control of
operation of washing machine by using fuzzy logic control and Arduino. This
control is with respect to the degree of dirt, amount of load and the type of
load, since the wash time is based on the amount of clothes to wash, the type
of load and the degree of dirt in clothes. First, the dirt in water is sensed
by optical sensor after 5 rotations which gives the output voltage in the range
of 0-5 volts. For high level of contamination of water, the voltage range is 0
to 2 volts and for low level of contamination the range is 4-5 volts
approximately. Secondly with respect to load, the supply current drawn increases as the load on the washing
machine increases. By sensing the amount of current and optical sensor output
voltage, the wash time is determined. So the control is done for both cases
i.e. based on dirt level and amount of load. For lightly loaded and less dirt
requires less wash time. For heavily loaded and more dirt condition wash time
is more. The wash time is varied in order to control the type of load. By
giving these signals (current and voltage) as input to Arduino we determine the
required amount of wash time for which the machine is operated. Thus, Fuzzy
logic controlled washing machine controller gives a correct wash time even
though a precise model of input and output relationship is not given.
