In the circuit, the 2N2222 transistor is shown as a switch, with an input resistor driving it and a second resistor driving the LED. You can also use a timer to control when the LED turns on and off. The schematic depicts the basic circuit of the BC547 as a switch, which contains two resistors for driving LEDs and a transistor bias terminal.Ĭurrent flows across the circuit when the switch is closed, and the transistor serves the function of a switch. This one has a higher gain due to the transistor architecture. The best voltage amplifier circuit that uses the NPN 2N2222 transistor is the common emitter arrangement. The diagram depicts an amplifier circuit using a 2N2222 transistor. The input resistor and capacitor will be used as bypass components, with the resistor acting as a biasing agent for the BC547 transistor.Īs a result, an audio signal received at the input is amplified and sent to the output speaker by the transistor. The diagram depicts a basic amplifier circuit that uses BC547 and only has four components.
