  วิธีทำ
เรากำหนดขาต่อ 7 Segment ว่า
pinMode(11, OUTPUT);   
pinMode(10, OUTPUT);
pinMode(9, OUTPUT);   
pinMode(8, OUTPUT);
pinMode(7, OUTPUT);   
pinMode(6, OUTPUT);
pinMode(5, OUTPUT);
จะขาไหนก็ได้
แล้วสวิตช์
pinMode(4, INPUT);
pinMode(1, INPUT);
ใน void set up
จากนั้นเขียน code สวิตช์ ขา 4แล้วเอาขาที่กำหนดมาใส่ตั้งแต่ 0-9
int XD = digitalRead (4);
 if (XD==0){
เอาขาที่กำหนดไว้ตั้งให้เป็นตัวเลข
เลข 0
   digitalWrite(11, HIGH);
    digitalWrite(10, HIGH);
    digitalWrite(9, HIGH);
    digitalWrite(8, HIGH);
    digitalWrite(7, HIGH);
    digitalWrite(6, HIGH);
    digitalWrite(5, LOW);
    delay(1000);
เลข 1
    digitalWrite(11, LOW);
    digitalWrite(10, HIGH);
    digitalWrite(9, HIGH);
    digitalWrite(8, LOW);
    digitalWrite(7, LOW);
    digitalWrite(6, LOW);
    digitalWrite(5, LOW);
    delay(1000);

    digitalWrite(10, HIGH);
    digitalWrite(9, HIGH);
    digitalWrite(8, HIGH);
    digitalWrite(7, LOW);
    digitalWrite(6, LOW);
    digitalWrite(5, HIGH);
    delay(1000);
เลข 4
    digitalWrite(11, LOW);
    digitalWrite(10, HIGH);
    digitalWrite(9, HIGH);
    digitalWrite(8, LOW);
    digitalWrite(7, LOW);
    digitalWrite(6, HIGH);
    digitalWrite(5, HIGH);
    delay(1000);
เลข 5
    digitalWrite(11, HIGH);
    digitalWrite(10, LOW);
    digitalWrite(9, HIGH);
    digitalWrite(8, HIGH);
    digitalWrite(7, LOW);
    digitalWrite(6, HIGH);
    digitalWrite(5, HIGH);
    delay(1000);
เลข 6
    digitalWrite(11, LOW);
    digitalWrite(10, LOW);
    digitalWrite(9, HIGH);
    digitalWrite(8, HIGH);
    digitalWrite(7, HIGH);
    digitalWrite(6,HIGH);
    digitalWrite(5, HIGH);
    delay(1000);
เลข 7
    digitalWrite(11, HIGH);
    digitalWrite(10, HIGH);
    digitalWrite(9, HIGH);
    digitalWrite(8, LOW);
    digitalWrite(7, LOW);
    digitalWrite(6, LOW);
    digitalWrite(5, LOW);
    delay(1000);
เลข 8
    digitalWrite(11, HIGH);
    digitalWrite(10, HIGH);
    digitalWrite(9, HIGH);
    digitalWrite(8, HIGH);
    digitalWrite(7, HIGH);
    digitalWrite(6, HIGH);
    digitalWrite(5, HIGH);
    delay(1000);
เลข 9
    digitalWrite(11, HIGH);
    digitalWrite(10, HIGH);
    digitalWrite(9, HIGH);
    digitalWrite(8, LOW);
    digitalWrite(7, LOW);
    digitalWrite(6, HIGH);
    digitalWrite(5, HIGH);
    delay(1000);     
จากนั้นเขียน code สวิตช์ ขา 4แล้วเอาขาที่กำหนดมาใส่ตั้งแต่ 8-1
 int DX = digitalRead (1);
  if (DX==0){
ใสตัวเลข 8-1
 เลข 8
    digitalWrite(11, HIGH);
    digitalWrite(10, HIGH);
    digitalWrite(9, HIGH);
    digitalWrite(8, HIGH);
    digitalWrite(7, HIGH);
    digitalWrite(6, HIGH);
    digitalWrite(5, HIGH);
    delay(1000);
เลข 7
    digitalWrite(11, HIGH);
    digitalWrite(10, HIGH);
    digitalWrite(9, HIGH);
    digitalWrite(8, LOW);
    digitalWrite(7, LOW);
    digitalWrite(6, LOW);
    digitalWrite(5, LOW);
    delay(1000);
เลข 6
    digitalWrite(11, LOW);
    digitalWrite(10, LOW);
    digitalWrite(9, HIGH);
    digitalWrite(8, HIGH);
    digitalWrite(7, HIGH);
    digitalWrite(6,HIGH);
    digitalWrite(5, HIGH);
    delay(1000);
เลข 5
    digitalWrite(11, HIGH);
    digitalWrite(10, LOW);
    digitalWrite(9, HIGH);
    digitalWrite(8, HIGH);
    digitalWrite(7, LOW);
    digitalWrite(6, HIGH);
    digitalWrite(5, HIGH);
    delay(1000);
เลข 4
    digitalWrite(11, LOW);
    digitalWrite(10, HIGH);
    digitalWrite(9, HIGH);
    digitalWrite(8, LOW);
    digitalWrite(7, LOW);
    digitalWrite(6, HIGH);
    digitalWrite(5, HIGH);
    delay(1000);
เลข 3
    digitalWrite(11, HIGH);
    digitalWrite(10, HIGH);
    digitalWrite(9, HIGH);
    digitalWrite(8, HIGH);
    digitalWrite(7, LOW);
    digitalWrite(6, LOW);
    digitalWrite(5, HIGH);
    delay(1000);
เลข 2
    digitalWrite(11, HIGH);
    digitalWrite(10, HIGH);
    digitalWrite(9, LOW);
    digitalWrite(8, HIGH);
    digitalWrite(7, HIGH);
    digitalWrite(6, LOW);
    digitalWrite(5, HIGH);
    delay(1000);
เลข 1
    digitalWrite(11, LOW);
    digitalWrite(10, HIGH);
    digitalWrite(9, HIGH);
    digitalWrite(8, LOW);
    digitalWrite(7, LOW);
    digitalWrite(6, LOW);
    digitalWrite(5, LOW);
    delay(1000);
จากนั้นเราก็ใส่
    digitalWrite(11, LOW);
    digitalWrite(10, LOW);
    digitalWrite(9, LOW);
    digitalWrite(8, LOW);
    digitalWrite(7, LOW);
    digitalWrite(6, LOW);
    digitalWrite(5, LOW);
เพื่อกันให้หยุดทำงานถ้าส​วิ​ดไม่ถูกกด
แล้วเราก็สร้างฟังก์ชั่นใหม่เพื่อจะได้ไม่งงการเขียน code
gHu (); แล้วเอาที่เขียนทั้งหมดใส่ใน void loop
จากนั้น เอา ภาษา C ไปใส่ Arduino พอกดสวิตช์ขา 1 7 Segment จะเป็นเลข 8-1 
กดสวิตช์ขา 4 7 Segment จะเป็นเลข 0-9
