Step by step procedures for making a simple music system using BT66T / UM66

We had already seen the circuit for making 'Jingle Bell' music using BT66T / UM66 in one of my previous blog. But, some of the beginners in electronic circuits may get confused a bit while doing the circuit. Here, we will see the step by step explanation of the procedures for making a simple music system using BT66T / UM66. Circuit require six simple components. They are

• a 10 K resistor
• a Press button switch
• a speaker (I am using a 4 Ohm, 3 Watts speaker)
• a BT66T  -  Music IC
• a 2SC9013  - Transistor

Circuit is done on a breadboard. Watch the following video demonstration to get the steps for completing the circuit.
