USING ABLETON WITH WIRELESS BUTTON!

Projects General Guidance
1

Hi there!

I would like to create 4 wireless buttons with Arduino Leonardo where:

  • If I press the button 1 the Pc press "a" on the keyboard, if I press button 2 "s", button 3 "d" and button 4 "f". (I need only 4 buttons)

-This button should be wirless. To do this I want to use 4 of these wirless button: Keyfob 4-Button RF Remote Control - 315MHz : ID 1095 : $6.95 : Adafruit Industries, Unique & fun DIY electronics and kits (I need to buy 4 of these because I can't adress the signal and I need 4 split buttons! Either do you have a better idea? ) and this receiver: Simple RF T4 Receiver - 315MHz Toggle Type : ID 1097 : $4.95 : Adafruit Industries, Unique & fun DIY electronics and kits.

To be more specif: I would like 4 split wirless buttons to activate some effects in a musical softwere called Ableton. I've already done this project but with the MakeyMakey and without the wirless buttons. Furthermore I would like that when I press the botton 1 the led 1 switch on and stay high until the next press on the button 1.

The questions are:

1_Do you think these Adafruit buttons are the best (easiest) choice?
2_Can I add 4 leds that become high when I use one of the buttons and stay high until press again the button? I need Feedback for the user!
3_Could you link me a project for emulate the keyboard using buttons and leds feedback?

Hope to be clear.

Thanks a loooooooooot!!! This will be a part of thesis so thanks again!!!

My $.02 - the arduino uno is so cheap and so small, I'd get an uno with a wifi or bluetooth shield as the remote, then mount 4 (or more) physical buttons on it. could even do IR on the uno, then buy a cheap IR receiver for your PC. kind of like a uno powered remote. maybe even the thumb joystick on the remote? not sure the benefit of "wireless buttons" over that - although they look cool and are smaller. using 4 different fobs to control one thing might be odd though.

as for the state of the led - depends on how you right the code, but sure - can make them stay "HIGH" until you press again, no problem.

the other part of your problem - displaying output on a PC - that im not sure. easy to do with the serial monitor - not sure if you are trying to display that in another program??
