как сделать светофор на arduino uno

вот скетч: int red = 11; int yellow = 10; int green = 9; void setup() { pinMode(red,OUTPUT); pinMode(yellow,OUTPUT); pinMode(green,OUTPUT); } void loop() { digitalWrite (red,HIGH); delay(2000); digitalWrite (red,LOW); delay(10); digitalWrite (yellow,HIGH); delay(2000); digitalWrite (yellow,LOW); delay(10); digitalWrite (green,HIGH); delay(2000); digitalWrite (green,LOW); delay(100); digitalWrite (green,HIGH); delay(1000); digitalWrite (green,LOW); delay(100); digitalWrite (green,HIGH); delay(1000); digitalWrite (green,LOW); delay(100); digitalWrite (green,HIGH); delay(1000); digitalWrite (green,LOW); delay(10); }
