I. Mica, decal
- Mua Mica về cắt theo hình mình thích (vuông, chữ nhật, tròn, hình hột xoài...)
Kích thước 1m2 X 2m4 có nhiều loại (1mm, 2mm, 3mm,...) và nhiều màu. Giá khoảng 700K
- Cắt, dán Decal:
Ta có thể đến chỗ cắt Decal nhờ họ thiết kế theo ý thích của mình hoặc mình tự thiết kế trên CorelDraw rồi đem đến cho họ cắt rồi đem về dán lên bảng Mica.

II. Khoan lỗ - gắn LED:
Có 2 cách gắn LED vào bảng là gắn từ sau tới và gắn tử phía trước để toàn bộ con LED nằm phía trên bảng Mica.
- Gắn từ phía sau: ta dùng mũi khoan đúng kích thước với LED (LED nhỏ 3mm, LED lớn hơn 5mm) tiến hành khoan lỗ rồi gắn LED vào.
- Gắn từ phía trước: Nếu LED 5mm thì khoan lỗ 3mm gắn LED vào rồi đổ keo cho chắc.

III. Đấu LED:
- Dùng định luật Ohm để tính.
VD: Ta có chữ cái gồm 11 LED, mỗi LED (A=15mA, V=3V) ta mắc như hình dưới.


Thông số LED 5L Siêu sáng tham khảo:
- Xanh lá, Trắng, Xanh dương: I=15mA, U=3V - 3,5V
- Đỏ, vàng : I=15mA, U=1,9V - 2,1V

IV. Phần mạch:
Đây là mạch đã hoàn thành:
