I need to design a circuit that has three LEDs, each LED has its own push button switch, but there is only one common buzzer.
Goal: when a push button is pressed its corresponding LED should glow along with the buzzer sound.
- Design the circuit with single battery source.
- Design the circuit with two battery sources such that when a push button is pressed LED should glow from one battery source and buzzer should sound from other battery source.
Please help me with either of the above two circuit diagrams.
