Here I have design a touch sensitive circuit diagram.For this circuit I have used a common transistor BC 547.Normally this circuit can be operated with 4.5 to 6 v.I suppose you will be able to do lots of things with this.I have used this circuit for my room light.So you also can use this circuit for your room light.
Note
# Use a pcb to build this circuit
# Don't supply more than 6V
