Seeking an Engineer to prototype a battery-powered, Arduino-based Bluetooth Keyboard Foot Pedal that pairs to a computer or mobile device and sends the letter [J] when pressed.
The user has to press [J] when his hands are full, so a footswitch would make life easier. User would switch on the pedal, pair it with his laptop or phone, then press the pedal each time he wants to send a [J].
Project largely involves following this tutorial, but enclosing the Bluefruit from view: https://learn.adafruit.com/bluefruit-bluetooth-wireless-foot-pedal-switch
- Engineer completes non-disclosure and assumes no ownership over schematic or product
- Engineer submits schematic / circuit diagram to Client along with simple description of function
- Engineer submits list of parts (x2) needed to Client; Client orders/ships parts to Engineer
- Engineer produces single prototype (for keeping); shares video of functioning pedal with Client
- Engineer produces a second prototype (for sending to Client); ships to Client
- Client confirms function of pedal
If the Engineer can detect a long-press (hold for 1 second?) of the pedal and send the [Spacebar] key instead of the [J] key, this would allow the switch to perform two functions.
I am not the expert, but I assume something like this pedal https://chicagodist.com/products/foot-switch would connect to a box containing http://www.amazon.com/Bluefruit-EZ-Key-Bluetooth-Controller-Industries/dp/B018A2SV00 and a battery, with an on/off switch and a Bluetooth pairing button. The pedal would ideally butt-up against the circuit box to appear as one unit, but may also be separated by a few inches of the pedal cable. The circuitry should be enclosed (not visible to user).
