DIY Homemade Melody Door Bell Circuit Diagram The following diagram shows how a UM66 IC musical tone generator can be used for door bell application. The diagram above depicts the proposed musical door bell circuit, the various stages may be understood with the following explanation.
The UM66T series is a CMOS LSI designed melody generator IC intended for various applications such as doorbells, phones, toys, musical bells, home security alarm systems, and burglar alarms.. It incorporates an on chip ROM programmed for musical performances and operates within a supply voltage range of 1.5V to 4.5V.. Equipped with a built in RC oscillator this compact melody module can be
Simple Musical Doorbell Circuit using IC UM66 Circuit Diagram
The straightforward design of a musical doorbell explained here can be easily built and installed in your house. The circuit basically comprises three stages viz: The Timer, The Monostable Multivibrator and the Tone Generator stage. The circuit is equipped with some outstanding features like interchangeable music chips, AC/DC operation and audio period time adjust facility. The circuit is very
The circuit for the musical doorbell can be seen below and is relatively simple. As pointed above, at the heart of the circuit is a very old melody generator chip - the BT66T (IC2). The BT66T is an easy to use little melody generator IC, mainly used in circuits where a melody has to be played as a notification for the user.
