You asking too much. :D

To interface DC Motor, see DC Motor Lesson.
To integrate timer, you don't need timer circuit, it just program, see Timer Lesson.

Boleh sape2 tlng buat litar yang mempunyai aplikasi mcm nie..ada kawalan manual untuk motor dc forward or reverse, pastu mempunyai timer dalam masa 1 jam dan mempunyai pengesan hujan..3 aplikasi dalam 1 litar..ada sesiapa blh tlng x??

Manual Control:
yang nie mcm biasa la kawal secara manual motor dc to forward atau reverse.

Timer:
Menggunakan masa maximum 1 jam, kemudian akan secara automatik mengerakkan motor..dan mempunyai limit switch.

Pengesan hujan :
Apabila pengesan hujan mengesan hujan, motor DC akan secara automatik bergerak..dan mempunyai limit switch juga..
Harap anda dapat membantu dalam permasalahan ini.

Mengabungkan 3 aplikasi dalam 1 litar..klu boleh x payah guna PLC atau microcontroller..

What is the purpose of doing so where you can save cost and time by using microcontroller? Really cannot help :mrgreen:

I think you'll have better luck if asking this question in google groups like sci.electronics.basics OR sci.electronics.design.... Experts there discuss discrete components circuit and they reject MCU or MPU questions. :twisted:

I have been a frequent visitor there and still IS and got many of my questions answered. Watch out for Phil Allison from Australia as he always like to use foul language if you ask stupid questions. John Fields and Rich Grise are helpful. One of my questions was answered by Winfield Hill (The co-author of "Art of Electronics") himself. If you're lucky, you might meet him there. ;)
