Simple FM Transmitter with one Transistor
FM Transmitter Circuit Working Explanation To make the Simple FM Transmitter, we are using the condenser microphone that provides the audio signal. When the audio signal is from the microphone, it converts the signal into an electrical signal and then that signal penetrates the base of the transistor which increases the amplitude of the signal.

Bird Microphone Transmitter 2N2222 PNP Transistor
This circuit is based on two NPN transistors of 2N2222 which is a low-power amplifier. At the first transistor stage, the input signal is preamplified and then the transistor T2 will Amplify the signal as a power amplifier and then amplified the signal to be modulated and transmitted through output as an antenna.
2N2222 NPN Transistor 5 or 10 Pack
Watch on The 2N2222 is an NPN bipolar junction transistor (BJT). BJTs can be used to amplify analog signals, but they can be used as switches as well. Here we'll show how to use as a switch. The example to show this will be based on lighting a bright LED that will need a voltage and current larger than what an Arduino UNO IO pin can supply.
