Automatic On/Off Washroom Light System

"Design a circuit diagram for an **Automatic On/Off Washroom Light System** using an IR sensor, IC CD 4017BE, BC 547 transistor, BT 136 TRIAC, 10µF capacitor, 1kΩ resistor, a light bulb (AC load), and a DC power supply (battery). The IR sensor connects to IC 4017, whose output drives the BC 547 transistor. The transistor controls the TRIAC to switch the light bulb. The battery powers the circuit. Include all connections and components with the AC load controlled by the TRIAC."
