5V Low Dropout Regulator Circuit using transistor and LED
Make 5V low dropout regulator circuit using transistor and LED lowest voltage input is 6V so across it is 1V only, make output is 5V 0.5A Read more
220V AC siren circuit using transistors
This AC 220V siren circuit is a simple siren that uses 220V AC as a power supply. It is small size and uses a piezo speaker cause use low power and saving. How it works This circuit is shown in Figure 1 which we use power source by reducing AC-voltage of 220 volts down by the resistors-R1, … Read more
