Quick Start.  Text here, pictures below.

FunKey has 18 alligator "ports", some designed for sending keystrokes to Scratch or other programs or languages, some designed for "unplugged" activities and inventions with no computer necessary.

Keystroke mode: attach alligator leads to any of these 12 ports: WASDFG UP DOWN LEFT RIGHT SPACE OR CLICK.  Attach another alligator to any of the "ground" holes at the bottom of the board.  Hold the ground lead in one hand and touch any of the other alligators to send the corresponding keystroke to the computer via the USB cable.  Attach the alligators to metal, foil, etc to make game controllers or musical instruments.

Sensor Keystroke Mode:  Attach any sensor to WASDFG UP DOWN LEFT RIGHT SPACE OR CLICK.  The "out" sensor connection goes to the port.  The - or gnd sensor connection goes to one of the connections at the bottom of the board.  The + or VCC sensor connection goes to one of the connections at the top of the board.  Triggering the sensor will send the corresponding keystroke to the computer via the USB cable.  For ANALOG sensors like light, moisture, heartbeat, connect the sensor to the H port.  It will send keystrokes 0 to 9 and A to Z to represent the analog sensor's value. Use for timing speed, controlling games, analog theremins, heartbeat charting, etc.

Unplugged Sensor/Output activities. No computer needed.  Power the board from USB or battery. On the right side of the board there are 6 ports H I J K L M.  Connect a sensor to H and it will control a servo motor attached to the I port.  Connect a sensor to J to control the output of K and on L to control the output of M.  Outputs on K and M can be LEDs, buzzers and very lightweight motors. (note: the H analog port is used both for unplugged and also for keystroke to Scratch.)  Activities:  EZPass, heartbeat meter, moisture meter, light meter, ...
