Boa tarde, pessoal. Eu preciso explicar cada detalhe desse código que vai ser usado num arduino para criar um relógio de LEDs mas não estou entendendo, então por isso venho aqui pedir para alguém me esclarecer sobre o código todo, por favor. int LED1 = 2; int LED2 = 3; int LED3 = 4; int LED4 = 5; int LED5 = 6; int LED6 = 7; int LED7 = 8; int LED8 = 9; int LED9 = 10; int LED10 = 11; int LED11 = 12; int LED12 = A1; int LED13 = A2; int LED14 = A3; int LED15 = A4; int LED16 = A5; int sensorPin = A0; unsigned int n,ADCvalue,propeller_posn; unsigned long previousTime = 0; byte hours = 12; // set hours byte minutes = 15; // set minutes byte seconds = 00; // set seconds int val; 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); pinMode(LED9,OUTPUT); pinMode(LED10,OUTPUT); pinMode(LED11,OUTPUT); pinMode(LED12,OUTPUT); pinMode(LED13,OUTPUT); pinMode(LED14,OUTPUT); pinMode(LED15,OUTPUT); pinMode(LED16,OUTPUT); pinMode(sensorPin,INPUT_PULLUP); if(hours == 12) hours = 0; } void loop() { val = digitalRead(sensorPin); while (val == LOW) { val = digitalRead(sensorPin); } if (millis() >= (previousTime)) { previousTime = previousTime + 1000; seconds = seconds+1; if (seconds == 60) { seconds = 0; minutes = minutes+1; } if (minutes == 60) { minutes = 0; hours = hours+1; } if (hours == 12) { hours = 0; } } propeller_posn=30; n=0; while(n < 60) { drawMinuteMarker(); if ((propeller_posn==0) || (propeller_posn==5) || (propeller_posn==10) || (propeller_posn==15) || (propeller_posn==20) || (propeller_posn==25) || (propeller_posn==30) || (propeller_posn==35) || (propeller_posn==40) || (propeller_posn==45) || (propeller_posn==50) || (propeller_posn==55)) drawHourMarker(); if ((propeller_posn==0) || (propeller_posn==15) || (propeller_posn==30) || (propeller_posn==45)) drawQuarterMarker(); if((propeller_posn == hours*5) || (( propeller_posn == 0 ) && (hours == 0))) drawHoursHand(); if(propeller_posn == minutes) drawMinutesHand(); if(propeller_posn == seconds) drawSecondsHand(); delayMicroseconds(140); displayClear(); drawInner_Circle(); delayMicroseconds(600); n++; propeller_posn++; if(propeller_posn == 60) propeller_posn=0; } val = digitalRead(sensorPin); while (val == HIGH) { val = digitalRead(sensorPin); } } //========================= void displayClear() { digitalWrite(LED1,LOW); digitalWrite(LED2,LOW); digitalWrite(LED3,LOW); digitalWrite(LED4,LOW); digitalWrite(LED5,LOW); digitalWrite(LED6,LOW); digitalWrite(LED7,LOW); digitalWrite(LED8,LOW); digitalWrite(LED9,LOW); digitalWrite(LED10,LOW); digitalWrite(LED11,LOW); digitalWrite(LED12,LOW); digitalWrite(LED13,LOW); digitalWrite(LED14,LOW); digitalWrite(LED15,LOW); digitalWrite(LED16,LOW); } void drawMinuteMarker() { digitalWrite(LED16,HIGH); } void drawHourMarker() { digitalWrite(LED15,HIGH); digitalWrite(LED14,HIGH); } void drawQuarterMarker() { digitalWrite(LED13,HIGH); digitalWrite(LED12,HIGH); } void drawHoursHand() { digitalWrite(LED1,HIGH); digitalWrite(LED2,HIGH); digitalWrite(LED3,HIGH); digitalWrite(LED4,HIGH); digitalWrite(LED5,HIGH); digitalWrite(LED6,HIGH); digitalWrite(LED7,HIGH); } void drawMinutesHand() { digitalWrite(LED1,HIGH); digitalWrite(LED2,HIGH); digitalWrite(LED3,HIGH); digitalWrite(LED4,HIGH); digitalWrite(LED5,HIGH); digitalWrite(LED6,HIGH); digitalWrite(LED7,HIGH); digitalWrite(LED8,HIGH); digitalWrite(LED9,HIGH); } void drawSecondsHand() { digitalWrite(LED1,HIGH); digitalWrite(LED2,HIGH); digitalWrite(LED3,HIGH); digitalWrite(LED4,HIGH); digitalWrite(LED5,HIGH); digitalWrite(LED6,HIGH); digitalWrite(LED7,HIGH); digitalWrite(LED8,HIGH); digitalWrite(LED9,HIGH); digitalWrite(LED10,HIGH); digitalWrite(LED11,HIGH); } void drawInner_Circle() { digitalWrite(LED1,HIGH); delayMicroseconds(30); digitalWrite(LED1,LOW); }
