Hi to everyone on the list. I am making an electronic programmer to replace the standard mechanical timer and take care of all the different wash cycles on a washing machine. This will mean different motor speeds, water temperatures, washing times etc. for different matereials. I would be pleased to hear from anyone who has done this, or similar control of a.c. devices with hints, tips advice etc as I am completely new to PIC's, although I have done some 'C' and Assembly language programming. I am aquiring a book in the next couple of days which should give me an introduction to the PIC. What is the best way of interfacing the 240 volt inputs from sensors and the 240volt outputs to motors, heaters etc. Maybe relays, triacs, SCR's. Any help or advice appreciated.
