FM radio tuner control through Max or other

February 16, 2006 | 1:30 pm

Hi Everyone
I’m looking for a way to digitally control an fm radion tuner, causing it to change stations by a specified amount every x seconds. Max solutions are definitely preferable, though any cheap hardware-software combination will do (the simpler the better). Perhaps even something like controlling a portable mp3 player’s built in fm tuner via usb. Any and all advice is welcome…

I was looking into building something similar actually, but didnt get a chance to try this out. But the solution I found which seemed the most viable was to use a USB infrared Dongle (about 5 quid from ebuyer and stuff) and control a hifi with a built in tuner, other than this you’d probably have to get your hands dirty and do some wiring (I was just as keen to avoid this). You could then send the information out from max to tell it to jjump to whatever points or move between them
Hope this is helpful

how did you send commands to Infrared dongle? using serial object or
some other way?

I presume it would be simple enough to do through the serial object, but once again alas I have had alot of University projects to get done so havent looked that deeply into it.
SOrry I cant be of more help as of yet

Thanks. Sorry for the late reply. The infrared solution sounds good, except I have no idea where to even begin learning how to communicate with the dongle from max, and how to set it so the radio picks up and "understands" the message… any advice would be welcome…

Well, I would imagine there is probably a set of software that will translate the infrared info, or you may be able to translate it using something like the serial object, however, as far as actually controlling the radio, some radio players and stuff come with remotes anyway, so maybe you could just manipulate one of those from max?

you can do it with a radio that uses a voltage to control a tuner
(essentially one with a traditional potentiometer) I’ve then used a
digital-> analogue converter (there are several out there) to
essentially act as the potentiometer. I managed to control a bank of
six radios. It was really important for my project to be able "sweep"
the fm band, so finding these older radios was important. The issue
with many new tuners is that they either mute when they step through
frequencies, and/or mute when you’re not "on" a channel with a strong
signal.

in fact – you can hear the project at this years’ Viper
festival in Basel, CH – march 16-20th

Hi all,

I have been attempting to use an arduino controlled fm receiver with Max, and I think I’m a bit over my head. The device I’m using is this: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=130795678219

I wonder if there is any simple way of sending information to control the receiver through the serial object in max. In the arduino code provided for the receiver it is possible to send message to select individual stations by typing into the serial monitor. It would be really great to simply send this information through Max, or to be able to move through the stations by altering the voltage of the analog pins.

I’m fairly experienced in Max, but I still have a lot of trouble conceptualizing communication with arduino, so any help would be great.
