Arduino(2) (FabLab)

I learned how to use 'if', 'digitalRead', 'analogread' and I used this to create the code that control the LED.

Schematics

control LED

Use the button to turn on the LED

control LED-2

Use variable resistor to adjust LED brightness

Code

control LED-2

Arduino
This adjusts the brightness of the LED
int led_pin = 11;
int input_value;
int brightness;

void setup() {
  // put your setup code here, to run once:
Serial.begin(9600);
pinMode(led_pin, OUTPUT);
}

void loop() {
  // put your main code here, to run repeatedly:
input_value = analogRead(A0);
brightness = map(input_value, 0, 1023, 0, 255);
analogWrite(led_pin, brightness);
Serial.println("input_value : "+String(input_value));
Serial.println("brightness : "+String(brightness));
}

control LED

Arduino
It use to turn on the LED
int led_pin = 13;
int sw_pin1 = 2;
int sw_pin2 = 8;
int sw1_value;
int sw2_value;

void setup() {
  // put your setup code here, to run once:
pinMode(led_pin, OUTPUT);
pinMode(sw_pin1, INPUT);
pinMode(sw_pin2, INPUT);
}

void loop() {
  // put your main code here, to run repeatedly:
sw1_value = digitalRead(sw_pin1);
sw2_value = digitalRead(sw_pin2);
if(sw1_value == LOW){ digitalWrite(led_pin, HIGH);
}
if(sw2_value == HIGH){ digitalWrite(led_pin, HIGH);
}
digitalWrite(led_pin, LOW);

}

Looking back on my childhood, I was happy when I was making something and I was proud of myself. "Making is instinct!"
