Transistors are used in almost every electronic device today. That’s why it is called “a revolutionary electronic component of this century”.Today we are going to build an awesome Transistor Project -Rain Sensor Alarm using two transistors and a Buzzer.
BC547 transistor pinout or pin diagram has three pins, starting from left: collector, emitter, and base respectively. It is available in two packages: SMD and TO-92 package. BC547 is an NPN Bipolar Junction Transistor. And like all other transistors, BC547 has three pins called the emitter, collector, and base respectively. BC547 transistor acts as a … Read more
