QUY TRÌNH TEST CẢM BIẾN SIÊU ÂM SRF05 BỞI LINH KIỆN TUHU

BƯỚC 1: Cấp điện áp 5VDC cho cảm biến.

BƯỚC 2: Test chức năng của cảm biến.

BƯỚC 3: Dán tem test và tem bảo hành, bàn giao lại cho bên phụ trách.

HƯỚNG DẪN SỬ DỤNG

BƯỚC 1: Kết nối cảm biến với Arduino.

- VCC của cảm biến kết nối với 5V trên Arduino

- GND của cảm biến kết nối với GNDtrên Arduino

- TRIG kết nối với D12

- ECHO kết nối với D13

BƯỚC 2: Kết nối Arduino với máy tính và nạp Code
