Wireless controlled servos from Guitar.

supper_slash

Ok so i am working on a project for my father. He is a guitarist, and i wish to build something small, that i can attach to his electric guitar, with momentary switches\buttons (around 4 of them, but ma-by more in the future) that will wirelessly control some servos. I am thinking optical is not an option because he may not be facing the receiver all the time.  I figure the maximum distance would be around 10 feet, but on average 3-5 ft.

Here are some of my goals:

  • Battery power-able. So it can be in a sleep mode often
  • Reasonably small sending unit, (and arduino with a shield, or at least a flat layout.) Better yet, an arduino DIP that i can use on a board solo after programming.
  • Fairly rugged as the sending unit will be on a guitar being played.

The fact is, i don't no much about sending data wireless.

The receiving unit can be larger, and powered. I just don't know If RF is an option, i don't think WiFi is. as i don't want to haft to set up a network and router and stuff, i just kinda need this plug and play. All i need it to do is.

Switch A press on.... off...

Switch B press on.....off...

Etc.

Just press to turn on than press again to turn off.

The wireless part is what has me stumped.

Any advice would be appreciated.

  • I would consider using a pair of Xbee modules. They are small wireless units that are relatively painless to set up. As a bonus, you may be able to get them to work via glue logic. I recommend watching Ben Hecks wireless mailbox episode for more details.

  • I'd look at the RF24 library for Arduino . the rf24 modules are small and cheap and there are plenty of simple tutorials for them so you should have no trouble finding an example that is close to what you want,

  • Hi,

              go to www.ciseco.co.uk and look at their SRF shield, priced at £9.99 including VAT in the UK.  Two of these attached to two Arduino UNO's or clones will easily accomplish what you are after.  You could use Ciseco's LLAP protocol to transmit the data from transmitter to receiver.  Alternatively and perhaps simpler you could use the Arduino EasyTransfer library.

     

    I have no connection with Ciseco other than being a fan and very impressed with their products.  In my opinion their is nothing better for radio communication and as the modules are transceivers, two way or multiple way communication is easy.  There is a lot of information on the Ciseco website.
