As far as I understand your post you would like to know how to use a microcontroller to turn someting on and off in a sequence.
To performe this task a microcontroller generates time intervals of say 1s and according to pre-programmed procedure sets outputs high or low. LOw output means the "light" is off, high output = "light" on.
If the microcontroller is connected to a radio link you can control its functions remotely i.e you can speed up the running sequence or just change it ..
