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.

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)
