I Put 2 Servo SG90 into this box and use android Mobile Phone to control House's Lamp
Thru Arduino+BT without any relay.You don't need to change your house original circuit
just plug in this box original Lamp Switch.This box is for 2 Power Switch .and I used the
generic mobile Phone USB changer as power source.
You 3DP STL file downlaod from below website:
