Header information
« on: May 20, 2016, 11:31:17 PM »
I've got a newish Makey makey, with key out/ms out/pgd and pgc pins.

Is there a site that will explain what these pins do or are for??

Hey Paul,

Oh sure, the header on the back works as follows:

- **KEY OUT** is activated when any of the alphanumeric keys are triggered.
- **MS OUT** is triggered when any of the mouse actions are triggered.
- **PGD** and **PGC** are for programming at the factory.
- **/RESET** resets the board when that pin is grounded.
- **5V** is power for small current motors and LEDs and is always running when the Makey Makey is plugged in.
- **GND** is the same as Earth on the bottom of the board and works to ground small motors and LEDs connected from either the MS OUT or KEY OUT pins.

To trigger small motors and LEDs, wire your device from either the **KEY OUT** or **MS OUT** to the **GND** pin.  The attachment will receive 5 volts of power from **KEY OUT** when any of the keys (spacebar, WASD, etc) on the Makey Makey are Earthed - regardless of remapping.  The same is true for **MS OUT**; when any mouse actions are Earthed (mouse directions, right click, left click), 5 volts are sent to your device.

Hope that helps!

If there was more space allowed in the header tag, this would be a lot easier Все об ароматах, косметике и парфюмерии
