Tick Tock Counter EEPROM

ขั้นตอนที่ 1 นำ Code ข้างล่างนี้โหลดลงบอร์ด

}

2.นำบอร์ด TickTock Shield มาประกอบร่างเข้ากับบอร์ด 

Arduino ดังรูปเลยค้าบบบ

3.ลองถอดสายบอร์ดออกเพื่อทดสอบว่ามีการ save 
ข้อมูลเข้าไปจริงไหม

4.ลองโหลดโค้ดลงบอร์ดีอกหนึ่งครั้ง
 
เพื่อดูว่าเลขที่เรากดไปครั้งล่าสุด กำลังแสดงอยู่หรือไม่

5.ลองทดสอบกับ labView ว่าค่าที่ได้แสดงใน 

read String ไหม
