I doing my final year project. I am busy designing a fountain involving electrically controlled valves and lights and one big pump to blast the water. We only controlling around 15 electronic valve by using relay.All need to continue doing fancy patterns in a nice sequence, all electronic.I have to use a controller board.What I really want to know is what controller can handle this as I need to be able to turn on and off approx. 15 switches in a specific sequence.I can look on the net for any similar things, please post or email me .I need suggestions on what microcontrollers I will need. I am hoping for a PIC 16F877A. The thing is, I don't actually know too much about PICs, and I am So, i hope that somebody would kindly send us the useful information on which PIC recommended and how we can control it.Thanks.
