    Hi
    Please help me redraw this electronic circuit after replacing the ( Electric Buzzer ) indicated with the letter ( B ) with a 5-pins Electric Relay.

    This is a Laser sensor circuit using a photo cell.

    I would really appreciate it if you guys help me with this one showing the new shape of the new connections after replacing the Buzzer with a Relay.

    Thanks a lot ..

    Connect one end of the relay coil to the +9V and the other end of the relay coil to the 8050 collector. Include a reverse-bias rectifier diode across the relay coil.
