The LCD does not turn on just blinks and the module works well for a moment and then turns off . can u help me please #1. : In this instructable you will learn how to communicate between Arduinos over a long distance up to 1.8km in open air.The HC-12 is a wireless serial port communication module that is … 5 years ago Please reply at the earliest!!!

It is digitally tunable from 87 MHz to 108 MHz, and Right and Left channels are available for stereo broadcast as well. 3 years ago Reply Connect the FM transmitter module with Arduino board as shown in hookup diagram. The cable, impedance matching, and height at which it is installed are also important. A Stable FM transmitter provides stable undisturbed output frequency even when the battery drains out. It can be used vertically as seen or horizontally depending upon which area one has to cover.

This can cover 5km range (long distance).

For example,  &756 is 75.6MHz, and &666 is out of range. The first two is the integer part    of new frequency (Unit: MHz), and the last one is the decimal part. This will likely encompass 5km spectrum (long range). The best way to increase the range of your FM transmitter is to use a matched antenna as per the impedance without which one gets very little range coverage. An FM transmitter is a gadget that uses the standards of frequency modulation to broadcast sound provided at … Is there any separate hardware required to interface the mic with module? Is it specified for these countries USAI want for INDIA, I changed the country name but its not coming. on hello how are you? 6 years ago Gain, SWR, etc are all not covered for simplification except the impedance(Z) of the antenna which is important. Yes you can , for floating point you can get any frequency you want. Secunderabad, Hyderabad, 500009, India.

I2C Pins SDA and SCL connected to A4 and A5 of arduino uno board because these two are I2C pins in uno board. In this tutorial, we are developing a project of a “Long Range FM transmitter Circuit”. It change depends on types of arduino board and micro controllers, check the pin details if other board is used.It just given for details and connections are made as shown in the hookup. If you are referring to 8 meters (about 25 feet) Technically it is okay according to FCC regulations Part 15. The RDS has to be injected at the varacap in the VFO circuit. 1 year ago 5 years ago Or is it me been THICK... A range of FM transmitters, antennas, cable, some spare power transistors are available at www.projectntraining.com.

There’s no need to buy kits, this tutorial includes the PCB layout and the schematics.

Technical Specifications of the Transmitter.

Arduino Hookup-FM transmitter.

Technology articles , technews, latest technology trends features in this site 805/8 Manasarobar Height-2 For this demo, input command format like &xxxx to set select band, (eg:if you want to set FM 95.6MHz,then input &0956 and send)./** check for data setting new frequency. 1 year ago "ERROR:Channel must be range from 70Mhz to 108Mhz. I'm doing this project and I've had a few problems. As a slight modification to what you've done, I am trying to connect a mic to the 3.5mm port so that I can transmit voice. or here Cable is Audio signal from the mic amplified through 9013 npn transistor and applied to the tx IC. L1 is equivalent to 5 turns of 0.7 mm enameled wire twisted on a 3 mm structure.
