สวัสดีครับ ใครพอจะแทรก หรือ รวม Library Arduino ได้บ้างครับ
ของผมจะดูอุณหภูมิผ่าน Eternet ผมทำได้แล้ว แต่ติดตรงที่จะให้ LED ติดเมื่ออุณหภูมิเกินค่าที่กำหนด และดับเมื่อถึงอีกค่านึง
ผมค่อนข้าง งงงงง เกี่ยวกับคำสั่ง if ไม่ว่าจะแทรกตรงไหนก็ไม่ได้ บางทีก็คอมพายได้แต่ดันไม่ทำงาน
ใครรุ้ช่วยบอกทีครับ ไปไม่ถูกจริงๆๆ นี่ครับ Library ผม และนี่ครับที่อยากจะแทรก
