Good evening !
I am actually working on a video switcher project, in which LED pushswitches are needed. I am desperately trying to control them via an Arduino UNO, but none of my trials seem to work properly. After doing some research on the Internet, I wired up this simple circuit, with some code.
What I am trying to do is just to get a reading from each button's state, and have it light up when it is pushed. What it actually does : lights up everything and stays like this no matter what I do.
Can somebody please help me ?
I join pictures of my circuit, and a small schematic (disclaimer : I am just a hobbyist !)
Here is my code :
int SW1 = 8;
int SW2 = 9;
int SW3 = 10;
int LED1 = 2;
int LED2 = 3;
int LED3 = 4;
void setup() {
pinMode(SW1, INPUT);
pinMode(SW2, INPUT);
pinMode(SW3, INPUT);
pinMode(LED1, OUTPUT);
pinMode(LED2, OUTPUT);
pinMode(LED3, OUTPUT);
digitalWrite(LED1, HIGH);
delay(200);
digitalWrite(LED1, LOW);
delay(200);
digitalWrite(LED2, HIGH);
delay(200);
digitalWrite(LED2, LOW);
delay(200);
digitalWrite(LED3, HIGH);
delay(200);
digitalWrite(LED3, LOW);
delay(200);
}
void loop() {
if (digitalRead(SW1 == HIGH)) {
digitalWrite(LED1, HIGH);
}
else if (digitalRead(SW1 == LOW)) {
digitalWrite(LED1, LOW);
}
if (digitalRead(SW2 == HIGH)) {
digitalWrite(LED2, HIGH);
}
else if (digitalRead(SW2 == LOW)) {
digitalWrite(LED2, LOW);
}
if (digitalRead(SW3 == HIGH)) {
digitalWrite(LED3, HIGH);
}
else if (digitalRead(SW3 == LOW)) {
digitalWrite(LED3, LOW);
}
}
