โค้ดแบบนี้ต้องต่อยังไงบ้างครับ

เบื้องต้นทำทีระบบครับเริ่มจาก Manual ก่อน อันนี้เสร็จหรือยังติดปัญหาหรือไม่

ลองศึกษาดูครับ

/**
 คือผมอยากทำ auto / manual ควบคุมผ่านแอพ blynk
โดยผมจะใช้ Widget timer1ตัว Button 2ตัว ตัวนึงเลือก auto ตัวนึงเลือก manual

การทำงานคือ

กดปุ่ม manual รีเลย์ทำงานทันที
กดปุ่ม auto ตั้งเวลาทำงานด้วย timer เมื่อถึงเวลาที่ตั้งไว้รีเลย์ถึงจะทำงาน

ผมรบกวนขอ Code ตัวอย่างการเขียนทีครับ
