  Blynk is a platform with iOS and Android apps to control
  Arduino, Raspberry Pi and the likes over the Internet.
  You can easily build graphic interfaces for all your
  projects by simply dragging and dropping widgets.

ขาดการเซต pinMode ว่า ขา 15 เป็น input หรือ output ครับ

ได้แล้วครับ ขอบคุณ

เยี่ยมมากครับ

ขอบคุณครับ จะเอาไว้มอนิเตอร์สภาพแวดล้อม โคกหนองนา ครับ ตามความสามรถตัวเองทำโปรแกรมแบบยากๆไม่เป็นครับ

สวยครับ จัดให้พอดีเต็มหน้า ก็ลงตัวแล้วครับ :+1:

ว่างๆ ถ่านมาชมกันบ้างนะครับ

ค่อยๆ ไต่ระดับขึ้นไปนะครับ เอาง่ายไว้ก่อน สะดวกที่สุดครับ
