Touch Key USB Shield UNO R3 Dev Board - Open

Have you seen the Makey Touch keyboard simulation? MaKey MaKey is a very simple circuit board that can make any objects as a computing input device.
That’s to say, it can make stairway into a piano, bananas into a keyboard, plasticine into a joystick or even your family into a musical synthesizer.
The principle is simple. It uses an ARDUINO microcontroller to simulate a keyboard and lead out several keys, replacing the switch with touch key.
The shield uses touch input, namely, a double-contact switch, leading out touch port and ground connected to two touch electrodes. Because of body-resistance, when you touch the two electrodes, there is a certain current flowing through between them, so can detect the touch event through the current detection.

• Compatible with UNO R3 and MEGA 2560 control board.

• XP and win7 system Drive-free auto-identification

• Identify six buttons at most

• Operating voltage: DC 5V

• Can set the 6 buttons output in the code

• Onboard comes with 2 anti-reversed interfaces, used to connect other devices.
