KeyeStudio EASY PLUG RJ11 Digital Push Button Module - Large Button Input for Arduino Learning Projects The KeyeStudio EASY PLUG RJ11 Digital Push Button Module is a simple digital input board for Arduino lessons, menu controls, counters, game inputs, and first electronics projects. Pressing the button outputs a HIGH-level signal according to the current listing, while releasing it outputs LOW. The EASY PLUG RJ11 format keeps wiring tidy when used with compatible KeyeStudio control boards. It can be combined with the RGB Full Color LED Module, relay outputs such as the 5V/12V Relay Module, or other OpenELAB controller projects. Use software debouncing for reliable button events and verify RJ11 pin sequence when mixing EASY PLUG modules with non-KeyeStudio boards. Technical Specifications Parameter Value SKU KY-KS0112 Brand KeyeStudio Product Type EASY PLUG RJ11 digital push button module Output HIGH when pressed, LOW when released per listing Supply Voltage 3.3V-5V Connector EASY plug / RJ11 Sensor Type Digital Input Device Large push button Host Platform EASY PLUG control boards, Arduino-compatible systems Software Need Debouncing recommended Board Layout & Label Guide Button Cap - Physical pushbutton input. RJ11 Connector - EASY PLUG cable interface. Signal Line - Digital output to controller. VCC - Supplied through RJ11 interface. GND - Ground through RJ11 interface. Indicator Area - Some boards show button state. Mounting Note - Secure the module to avoid cable strain. Compatibility Note - RJ11 pinout must match the control board. Application Scenarios 1. Arduino Digital Input Test Read the button output and print its state. const int sensorPin = 2; void setup() { Serial.begin(115200); pinMode(sensorPin, INPUT); } void loop() { Serial.println(digitalRead(sensorPin)); delay(100); } 2. LED Event Indicator Turn on an LED when the module output is pressed. const int sensorPin = 2; const int ledPin = 13; void setup() { pinMode(sensorPin, INPUT); pinMode(ledPin, OUTPUT); } void loop() { digitalWrite(ledPin, digitalRead(sensorPin)); } 3. MicroPython GPIO Monitor Monitor the digital signal from a Pico-style board. from machine import Pin import time sensor = Pin(15, Pin.IN) while True: print(sensor.value()) time.sleep(0.1) Packing List 1 x KeyeStudio EASY PLUG RJ11 Digital Push Button Module FAQ Q: What does the button output?A: The listing says HIGH when pressed and LOW when released. Q: What connector does it use?A: EASY PLUG RJ11. Q: Can I use it with Arduino?A: Yes, through a compatible EASY PLUG interface or correct RJ11 pinout. Q: Do I need debounce?A: Yes, debounce is recommended. Q: Can it control a relay?A: Yes, through microcontroller code. Q: Is it analog?A: No, it is digital. Q: Why does it read backward?A: Check input mode and wiring pinout. Q: Can it be panel mounted?A: It can be secured in a project if the module and cable are mechanically supported.
