I am researching the feasability of building a wireless arcade controller. Many of the current wireless controllers use hacked keyboards to accomplish the task (I am not a fan of this method).
I looked into using an Arduino BT but I cannot seem to find a stockist and the Blue Tooth is not suitable for HID emulation. Which leaves back at the
Blue SMiRF HID option. I have a Arduino Mega 2560 R2 which a received a while back, so I am thinking of using that in conjunction with the Blue SMiRF HID instead of the ProMicro.
I will order the Blue SMiRF HID over the next few days and have a play and see what comes of it.
