ว่าด้วยเรื่อง"Arduino Pro Mini - Upload error"
ผมไม่เคยใช้ Arduino แต่...เคยเรียนมาบ้างนิสหน่อย
ผมจะทำ Project. - Multi Glasses (แว่น มัลติมิเตอร์)
เนื่องด้วยผมเห็นในเว็ป https://www.instructables.com/id/Arduino-Data-Glasses-for-My-Multimeter/?fbclid=IwAR2YxyNhvFMhYU0gfvzbbVdNDea08_nneEy8OkieFEEdk4UbW09BSCl5lnw คือ วัดค่าต่างๆ ด้วยมัลติมิเตอร์ แล้วให้แสดงผลบนแว่นตา/จอแสดงผลที่เราทำขึ้นมา
แต่ตอนนี้เกิดปัญหา คือ Verify ผ่าน แต่...Upload ไม่ผ่านครับ (ขึ้นข้อความ สีส้ม)

Problem uploading to board.  See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.
ต้องแก้ไขยังไงขอรับบ
