CODE | How to Connect Remote Control - Arduino Project 047
In the first time I purchase this remote, I don't know why the operating mode is only non-latched, I was wondering why?. Maybe because of the cheap price, so the producer doesn't add a relay to it. So, then I try to find a way so this remote can be used for controlling power plug with latched operating mode (instead of non-latched mode).

// constants won't change. They're used here to set pin numbers:
const int button1 = 6; // the number of the pushbutton pin
const int button2 = 7;
const int ledPin1 = 8; // the number of the LED pin
const int ledPin2 = 9;
// Variables will change:
int ledState1 = HIGH; // the current state of the output pin
int ledState2 = HIGH;
int buttonState1; // the current reading from the input pin
int buttonState2;
int lastButtonState1 = LOW; // the previous reading from the input pin
int lastButtonState2 = LOW;
// the following variables are unsigned long's because the time, measured in miliseconds,
// will quickly become a bigger number than can be stored in an int.
unsigned long lastDebounceTime = 0; // the last time the output pin was toggled
unsigned long debounceDelay = 50; // the debounce time; increase if the output flickers
void setup() {
pinMode(button1, INPUT);
pinMode(button2, INPUT);
pinMode(ledPin1, OUTPUT);
pinMode(ledPin2, OUTPUT);
// set initial LED state
digitalWrite(ledPin1, ledState1);
digitalWrite(ledPin2, ledState2);
}
void loop() {
// read the state of the switch into a local variable:
int reading1 = digitalRead(button1);
int reading2 = digitalRead(button2);
// check to see if you just pressed the button
// (i.e. the input went from LOW to HIGH), and you've waited
// long enough since the last press to ignore any noise:
// If the switch changed, due to noise or pressing:
if (reading1 != lastButtonState1) {
// reset the debouncing timer
lastDebounceTime = millis();
}
if ((millis() - lastDebounceTime) > debounceDelay) {
// whatever the reading is at, it's been there for longer
// than the debounce delay, so take it as the actual current state:
// if the button state has changed:
if (reading1 != buttonState1) {
buttonState1 = reading1;
// only toggle the LED if the new button state is HIGH
if (buttonState1 == HIGH) {
ledState1 = !ledState1;
}
}
}
// set the LED:
digitalWrite(ledPin1, ledState1);
// save the reading. Next time through the loop,
// it'll be the lastButtonState:
lastButtonState1 = reading1;
// If the switch changed, due to noise or pressing:
if (reading2 != lastButtonState2) {
// reset the debouncing timer
lastDebounceTime = millis();
}
if ((millis() - lastDebounceTime) > debounceDelay) {
// whatever the reading is at, it's been there for longer
// than the debounce delay, so take it as the actual current state:
// if the button state has changed:
if (reading2 != buttonState2) {
buttonState2 = reading2;
// only toggle the LED if the new button state is HIGH
if (buttonState2 == HIGH) {
ledState2 = !ledState2;
}
}
}
// set the LED:
digitalWrite(ledPin2, ledState2);
// save the reading. Next time through the loop,
// it'll be the lastButtonState:
lastButtonState2 = reading2;
}
