Hello there,
This purpose of this circuit is to switch on the bulb during nighttime and switch off the bulb during daytime. But so far i tested it on the bread board and it couldnt work. I dont know whether it's my personal problem or the schematic problem, can anyone help me on this?? plus, I would like to add a timer of 5hours to the circuit. The main purpose of the timer is to automatically switch off the circuit after 5hours ( assuming that the person sleeps 5hours after it's dark.) and repeats the cycle daily. A friend of mine suggested that i should put a timer in between the Zener Diode and the BC547 Transistor. But i'm unsure of the value. Just now when i was experimenting, the whole building short-circuited thrice. HELP PLS.... if possible pls attach a schematic as well.. thanks. my dateline is tomorrow =(
