LS 3 PCS DIY Keyes Modules for Arduino (KY0038)

Specifications: Working voltage: 3.3V-5V(DC) Interface: 3PIN interface Input signal: digital signal Size: 31*21mm Product Introduction The module uses a triode to drive the LED to operate, and controls the LED changes by inputting signals to the IN pin of the module. 1.Pin IN: LED switches control pin, high level lightens LED, low level goes off 2.Pin VCC: Power input pin 3.Pin GND: Ground pin Using instruction 1、Input the high level of 3.3V-5V through the IN pin, LED lightens. Input the low level of 0V through the IN pin, LED goes out. 2、Input the PWM signal in IN pin，it can control the luminance and produce gradual change. 3、Module with two location holes which is convenient to fixate on other equipment. 4、Module uses XH2.54-3P standard wiring terminal. Package: 3 x LED Module 1x XH2.54-3P standard wiring
