Listen using any FM receiver such as your car or pocket radio receiver - this is an easy way to transmit audio up to about 10 meters / 30 feet away.This transmitter even has RDS/RBDS support - that's text/data transmissions that many modern FM receivers support. You can transmit just about any text you want, set the station identifier as well as the 'freeform' buffer.Best of all, you'll be up and running in minutes with our awesome Arduino library, example code and tutorial! It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. Have an amazing project to share? The radio supports a range of frequencies from 87.5mhz to 108mhz and you can scan them all with this code: The higher the dBuV noise value the stronger the signal and better chance there's a real station broadcasting there. You have been successfully subscribed to the Notification List for this product and will therefore receive an e-mail from us when it is back in stock! FM transmitter project from Tobias Mädel.. FMBerry is a piece of software that allows you to transmit FM radio with your Raspberry Pi. Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. @adafruit @raspberry_pi…. If you order a full 4 or 5 meters, you get the full reel with both connectors installed (like the pic below). This may also require enabling I2C on your platform and verifying you are running Python 3. Remember the range of these low power FM transmitters is limited and you might need the radio in the very same room or close by to pick up the signal. Each Friday is PiDay here at Adafruit! However at 107.35mhz the signal has a much smaller noise value of 29 and likely indicates an unused frequency. Just connect power and speakers or headphones. (It's how some car radios can display the FM station and current song playing). Connect a jumper cable to header 7 of the Raspberry Pi, the jumper cable acts as the transmitter for Radio. $2.95.

Simply read the input_level property to see the audio level (in dB) and the audio_signal_status property to check if there are problems with the signal: Notice the input level is around -16 dB which is a typical value for audio (lower values mean less volume / input level and higher values up to 0 or more mean very loud input). We can simply attach a normal wire of 20 cm maximum to this pin to act as an antenna. What to do?? Become your very own pirate radio station with this FM radio transmitter.

See the video below for a demonstration and head over to GitHub for the code and build instructions. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. Notice in the screen shot above 107.7mhz has a strong signal with noise value of 45 dBuV, this makes sense because a nearby FM station, Seattle's 107.7mhz FM The End, is broadcasting at that frequency. Sorry, the comment form is closed at this time. Try cranking up the audio source volume and notice the audio level value increases and the overmodulation bit turns on to indicate the volume is too high (remember a value 4 or greater means the input is overmodulating): You should aim to keep the input level around -20 to -10 dB and ensure the overmodulation bit isn't set (if it is then the volume is too high). DCF77 (Germany), WWVB (US), MSF (UK), or JJY (Japan)? Bluetooth Audio FM Transmitter for Raspberry Pi 2 & 3: Part 1 #piday #raspberrypi #iLuvPi2 #Pi3 @Raspberry_Pi Nice instructional video from Novaspirit Tech on YouTube : This is a tutorial on converting your raspberry pi to an fm radio transmitter by just added a wire to gpio 4 and some code. Finally the RDS features of the Si4713 allow you to transmit data along with the FM audio signal. Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Cool project from RaspberryHacker on instructables. In addition it also shows basic usage of the GPIO outputs of the Si4713 with the gpio_control and gpio_set functions--these aren't commonly used but are available if you need a couple small outputs from the board. #Python #Adafruit #CircuitPython @micropython @ThePSF. You'll need to install the Adafruit_Blinka library that provides the CircuitPython support in Python.
