This circuit uses a 45-0-45 transformer, BD243 transistor, and several other components to control multiple LEDs simultaneously or individually.

The circuit consists of:

- 45-0-45 transformer (step-up voltage)
- BD243 transistor (switching component)
- 100 ohm resistor (base of transistor)
- 1N4007 diode (output stage)
- 160V 100uF capacitor (output stage)
- 1k ohm resistor (current limiting)
- 3.7V power supply (positive to transformer, negative to transistor emitter)

The circuit allows for:

- Simultaneous lighting of multiple LEDs
- Individual lighting of one LED at a time

This versatile circuit is perfect for DIY projects requiring multiple LED control. By adjusting the components and connections, you can customize the circuit to suit your specific needs.
