Information

KY-029 2-color [Red+Green] 3mm LED Module
LED-Module which contains a red and a green LED. These are
connected with a common cathode.
Depending on the input voltage, a resistor can be necessary
① - LED Gren
② - LED Red
③ - GND
KY-031 Knock-Sensor Module
If the sensor is exposed to a knock/shock, both output pins
are connected.
① - GND
② - +V
③ - Signal
KY-032 Obstacle Detecon Module
If the emied infared light hits an obstacle, the light is being
reected and detected by the photodiode. The detecon rage
can be controlled with the two controllers.
① - [EN]
② - digital signal
③ - +V
KY-033 Tracking Sensor Module
The sensor-module recognizes if a light-reecng or light-
absorbing surface is in front of the sensor.
The digital output is giving out the result.
This e.g. can be used to follow a line.
The sensivity of the sensor can be controlled with the con-
① - Signal
② - +V
③ - GND
KY-034 7 color LED Flash-Module
If this module is powered, a sequence of color-changes is
emied by the LED.
This contains 7 dierent colors.
Depending on the input voltage, a resistor can be necessary
① - GND
② - [N.C.]
③ - Signal
