Fm transmitter circuit

Fm transmitter circuit Power supply :- Using power supply stable DC voltage 2 V to 3.7 V max. You can only use battery because battery is perfect for this circuit battery output doesn't any noise. Components :- Transistor BC 547 , Resistance 100 ohm , 4.7 K ohm . Capacitor 1nF, 47pF, 22pF. Inductor 1uH. Condenser mic any . Resistance :- Using resistance 100 ohm +-5% changing 1/3 watt, 4.7 K ohm +-5% changing 1/3 watt. Capacitor :- 1nF this capacitor number 102 non-polar, 22pF this capacitor number 22 non-polar, 47pF this capacitor number 47 non-polar. Inductor :- This part important part for any transmitter circuit, 1uH 5Turn 24SWG. Transistor :- BC 547 is an NPN Bipolar junction transistor. It is commonly used to amplify current. A small current at its base controls a larger current at collector & emitter terminals. It has a transition...

Automatic home appliances

Automatic Home Appliances Remote control electrical appliances Setting up IR sensor connection to Atmega 328P is very simple. Beside VCC and GND pin , the sensor has only one output pin that should be connected to one of digital pins of the Atmega 328P. HC - 05 has red LED which indicates connection status, whether the Bluetooth is connected or not. Before connecting to HC - 05 module this red LED blinks continuously in a periodic manner. When it gets connected to any other Bluetooth device, its blinking slows down to two seconds. This module works on 3.3 V - 6V but you can use only 5V DC. this module use any Serial AMS1117 is a popular SMD package 3-pin voltage regulator that is available in many models for fixed and adjustable voltage requirements. The IC can deliver a maximum current of 1A and the output voltage can vary from 1.5V to 5V. ...
