In this video I make a custom shield for the Arduino Uno using a CNC router. I designed the PCB using QCAD. Music by me.
Code as follows:
//Knight Rider
int led1 = 1;
int led2 = 2;
int led3 = 3;
int led4 = 4;
int led5 = 5;
int led6 = 6;
int led7 = 7;
int led8 = 8;
// the setup routine runs once when you press reset:
void setup() {
pinMode(led1, OUTPUT);
pinMode(led2, OUTPUT);
pinMode(led3, OUTPUT);
pinMode(led4, OUTPUT);
pinMode(led5, OUTPUT);
pinMode(led6, OUTPUT);
pinMode(led7, OUTPUT);
pinMode(led8, OUTPUT);
}
// the loop routine runs over and over again forever:
void loop() {
digitalWrite(led1, HIGH);
delay(75);
digitalWrite(led1, LOW);
delay(10);
digitalWrite(led2, HIGH);
delay(75);
digitalWrite(led2, LOW);
delay(10);
digitalWrite(led3, HIGH);
delay(75);
digitalWrite(led3, LOW);
delay(10);
digitalWrite(led4, HIGH);
delay(75);
digitalWrite(led4, LOW);
delay(10);
digitalWrite(led5, HIGH);
delay(75);
digitalWrite(led5, LOW);
delay(10);
digitalWrite(led6, HIGH);
delay(75);
digitalWrite(led6, LOW);
delay(10);
digitalWrite(led7, HIGH);
delay(75);
digitalWrite(led7, LOW);
digitalWrite(led8, HIGH);
delay(75);
digitalWrite(led8, LOW);
delay(10);
}
