Hello, I`m new to this community, but Im asking for your help.

I must design a washing machine with microcontroller, my choice is PIC18F4550. My problem is that I cant find schematics for the peripheral devices.

For now I think to use those:

electric motor
door lock
heater
water pump for dirt water
water pump for water filing
temperature sensor
GSM module (little fancy)
LCD display
tachogenerator


I searched for washing machine schematics, but I found only for old models or block diagrams.

 

Hello,

How did you search?
I just found this:

You can also take a look at the different manufacturers manuals:

Thank you, I was searching for each component separately, and the most results in Google was for some companies that are producing these parts.
