Tự làm hệ thống PHÁT HIỆN KHÍ GAS - Phòng chống cháy nổ - Cảnh báo bằng tin nhắn 

em nạp code esp32 nó bị lỗi như nào là sao ạ C:\Users\duong\OneDrive\Documents\Arduino\libraries\ESP32Servo\src\ESP32PWM.cpp: In destructor 'virtual ESP32PWM::~ESP32PWM()': C:\Users\duong\OneDrive\Documents\Arduino\libraries\ESP32Servo\src\ESP32PWM.cpp:50:17: error: 'ledcDetachPin' was not declared in this scope; did you mean 'ledcDetach'? 50 | ledcDetachPin(pin); | ^~~~~~~~~~~~~ | ledcDetach C:\Users\duong\OneDrive\Documents\Arduino\libraries\ESP32Servo\src\ESP32PWM.cpp: In static member function 'static double ESP32PWM::_ledcSetupTimerFreq(uint8_t, double, uint8_t)': C:\Users\duong\OneDrive\Documents\Arduino\libraries\ESP32Servo\src\ESP32PWM.cpp:57:16: error: 'ledcSetup' was not declared in this scope 57 | return ledcSetup(chan, freq, bit_num); | ^~~~~~~~~ C:\Users\duong\OneDrive\Documents\Arduino\libraries\ESP32Servo\src\ESP32PWM.cpp: In member function 'double ESP32PWM::setup(double, uint8_t)': C:\Users\duong\OneDrive\Documents\Arduino\libraries\ESP32Servo\src\ESP32PWM.cpp:148:17: error: 'ledcDetachPin' was not declared in this scope; did you mean 'ledcDetach'? 148 | ledcDetachPin(pin); | ^~~~~~~~~~~~~ | ledcDetach C:\Users\duong\OneDrive\Documents\Arduino\libraries\ESP32Servo\src\ESP32PWM.cpp:149:30: error: 'ledcSetup' was not declared in this scope 149 | double val = ledcSetup(getChannel(), freq, resolution_bits); | ^~~~~~~~~ C:\Users\duong\OneDrive\Documents\Arduino\libraries\ESP32Servo\src\ESP32PWM.cpp:153:16: error: 'ledcSetup' was not declared in this scope 153 | return ledcSetup(getChannel(), freq, resolution_bits); | ^~~~~~~~~ C:\Users\duong\OneDrive\Documents\Arduino\libraries\ESP32Servo\src\ESP32PWM.cpp: In member function 'void ESP32PWM::adjustFrequencyLocal(double, double)': C:\Users\duong\OneDrive\Documents\Arduino\libraries\ESP32Servo\src\ESP32PWM.cpp:170:17: error: 'ledcDetachPin' was not declared in this scope; did you mean 'ledcDetach'? 170 | ledcDetachPin(pin); | ^~~~~~~~~~~~~ | ledcDetach C:\Users\duong\OneDrive\Documents\Arduino\libraries\ESP32Servo\src\ESP32PWM.cpp:174:17: error: 'ledcAttachPin' was not declared in this scope; did you mean 'ledcAttach'? 174 | ledcAttachPin(pin, getChannel()); // re-attach the pin after frequency adjust | ^~~~~~~~~~~~~ | ledcAttach C:\Users\duong\OneDrive\Documents\Arduino\libraries\ESP32Servo\src\ESP32PWM.cpp: In member function 'void ESP32PWM::attachPin(uint8_t)': C:\Users\duong\OneDrive\Documents\Arduino\libraries\ESP32Servo\src\ESP32PWM.cpp:235:17: error: 'ledcAttachPin' was not declared in this scope; did you mean 'ledcAttach'? 235 | ledcAttachPin(pin, getChannel()); | ^~~~~~~~~~~~~ | ledcAttach C:\Users\duong\OneDrive\Documents\Arduino\libraries\ESP32Servo\src\ESP32PWM.cpp: In member function 'void ESP32PWM::detachPin(int)': C:\Users\duong\OneDrive\Documents\Arduino\libraries\ESP32Servo\src\ESP32PWM.cpp:263:9: error: 'ledcDetachPin' was not declared in this scope; did you mean 'ledcDetach'? 263 | ledcDetachPin(pin); | ^~~~~~~~~~~~~ | ledcDetach exit status 1

bộ kit được nạp sẵn code chưa ạ

mik muốn mua riêng "Mạch Phát Hiện Rò Rỉ Khí GAS BLK" có bán không ad

7:30 kh có arduino thì ls ạ

anh ơi anh có só đồ nguyên lý của cảm biến khí gas này kh anh cho em xin với

Có bán ko vậy ạ

😮😮😮🔧🔨😍😍😎😎👍👍👍👍

đỉnh của chóp, order hàng ở đâu vậy ạ

anh ơi nếu không phải arduino mà em dùng pic 16f877a được không ạ

Bộ này thay vì dùng mạch arduino nano thì mình dùng mạch arduino uno được ko ạ

Sản phẩm tuyệt vời .Mua hàng thế nào

Bên mình có nhận in mạch ko shop

cho em hỏi shop mún vào nhóm zalo tư vấn bên mình làm sao ạ

Hay quá shop ơi

có kèm theo cod kg shop

Đỉnh quá shop ơi

hay quá ❤

Rất tuyệt vời
