Available sensors and outputs in the kits

Sensors and outputs come with "header pins" which are directly connected to the FunKey Super board with the supplied header cable connector "female/female" wires.  Each sensor or output device has a slightly different arrangement of these three connections, but they are simply marked and easy to connect.  Positive is marked either VCC or +.  Negative is marked either GND or -.  The signal connector is marked either S, or OUT.  Use the cables to connect these pins to the pins on the FunKey Super board, making sure to attach S to S, + to + and - to -.  Some sensors have two choices for signal, which may be marked A0 and D0.  You can use either one, depending on your goal.  The A0 gives continuous analog value, while the D0 gives an on/off value depending on whether the sensor value has crossed a threshold, and this threshold can be adjusted by turning the trim pot with a small screwdriver.   Some sensors and some outputs have only two connections.  For switchlike sensors such as the tilt sensor, connect either wire to the S connection on any port of the FunKey Super and connect the other wire to either the + or -.  Hover over any picture for a description, and click any picture for an enlarged view.  For the LEDs, connect the long lead (+) to the S, and the short lead (-) to the -.

Light Sensor
Light Sensor

The light sensor measures the amount of light that falls on it. It has an analog output as well as a digital output and the trim pot can be used to set the trigger threshold. It can be used as an interactive control or as a proximity or "line following" detector. Its response can be "focused" by placing a black tube, straw or tape as a "blinder" on the photocell so it can only see "forward" and does not detect light coming in from the side.

Touch Sensor
Touch Sensor

This touch sensor can be triggered by simply touching the circle, or even coming close to it. Its output is a digital on/off signal.

Proximity Sensor
Proximity Sensor

This on/off sensor detects whether an object is close to it. Some slight adjustment of distance is possible.

Temperature Sensor
Temperature Sensor

Changes values as the temperature changes. Has an analog output as well as a digital output. The trim pot is used to adjust the threshold of the digital output when a given temperature is reached.

Heartbeat Sensor
Heartbeat Sensor

This is a heartbeat detector which senses when placed on the skin. Although its range of variation is rather narrow, you can detect a heartbeat pulse accurately.

Motion Sensor
Motion Sensor

This on/off sensor detects human or animal movement in its very wide field of view. It's similar to security motion detectors. When it detects a movement, its signal goes "high" until there is no more movement detected. It takes several seconds to reset itself "low". Its connections are not marked, so refer to this picture. From this view, the left pin is +, the middle pin is signal and the right pin is -.

Battery Box
Battery Box

The battery box takes 3 AA cells and powers the board so you can create inventions and interactive projects that don't need a computer. The wires and connector are somewhat delicate, so use them with care.

Moisture Sensor
Moisture Sensor

This sensor measures the amount of water or moisture when inserted into the dirt of a plant pot, or when an absorbent material is placed across its contacts. It will also measure the amount of moisture on the skin, which varies from person to person and at different times. Some claim that skin moisture changes when people stray from the truth.

Servo Motor
Servo Motor

This special motor called a servo can be controlled to any position over about 140 degrees, or used as an "on/off" mode which it goes from one position to the opposite. It has a built-in cable which has the correct layout to connect it directly to a port, but make sure to align it in the right direction: Orange is S, red is + and brown is -. If you are using the "i/o special" FunKey Super mode, the servo only works on the W port, and is controlled by a sensor on the H port.
