hihi ko biết j nhưng mà mấy bạn mới học vào nhìn thất cái code phát ốm lun sao ma hiểu dc hihi??Comment
-
hihi mình cũng mới học nên chịu đấy hi jo muôn hoc vdk mà ko biết học cái j?ko làm thế nào mấy bạn viết code giỏi thi lần sau đăng code viết chú thích đằng sau câu lênh để minh học với ??ko minh nhin hoa hết mắt hiComment

có bác nào biết ko chỉ dùm em với ^^,Comment

phần led hiển thị đâu hả bác?Nguyên văn bởi chumanh Xem bài viếtXem chừng là diễn box 8051 đang sôi động với đồng hồ số và đo nhiệt độ các loại
, hôm nay rảnh ngồi send cho ae nào quan tâm tới vấn đề này. Một cái project mình làm đầy đủ cả, bạn nào thích thì load về lắp chơi nhé.

Trả lời cho Đấu tắt điện cho máy tính bảngBqv cáo lỗi vì chưa đủ khả năng diễn giải để người đọc hiểu. Người làm kỹ thuật sâu đôi khi như thế đó. Về việc nạp pin không vào dù cell mới, khả năng cái mạch quản lý đó đã hỏng - cũng chính là nguyên nhân đám cell cũ hỏng từ đầu.06-12-2025, 17:17 -
Trả lời cho Xin hỏi về mạch thu FM/AM trong catsetteTheo tôi, nó chỉ là cái Tuy- ê - nơ, hoặc là khối Trung Văn Tần, nó một phần trong cái Da đì ô thôi. Vì có thấy một chỗ có ba chân hàn, giiống như chân Cờ rít sờ tăng 455 ki nô hẹc. Còn khối Tuy ê nơ thì không nhìn thây cái Di ốt Va di cáp...05-12-2025, 19:59 -
Trả lời cho Đấu tắt điện cho máy tính bảngCó vẻ ngoài hiểu biết của mình rồi. Cuối cùng mình quyết định tìm mua 2 pin trên Shopee, giá 200K thay vào. Tuy nhận pin được 1%, sạc mãi không vào nhưng cũng mở được máy lên. Vậy cũng tạm. Cảm ơn bạn đã hỗ trợ nhé....04-12-2025, 01:27 -

Trả lời cho Làm thế nào để check IC LM358Để check IC sống hay chết thì đơn giản : bạn lắp cái mạch ( khuếch đại hoặc dao động ) chạy bằng con IC đó ,nhưng vị trí IC thì lắp cái đế .... thế là cứ cắm rút thì biết .

Tình hình là em có mua mạch 3s về để hàn vào khối pin 12v, hàn xong em đo tại các chân từ B-, B1, B2, B+ thì điện áp pin vẫn đủ 12,6v, nhưng tại 2 chân ra P- P+ thì đo chỉ được 6,3v là bị sao các bác, và chân P- P + này đồng thời là chân sạc xả thì mình cắm sạc xả cùng lúc được ko ạ
