matters needing attention

FAQ: does Arduino display connection 8266 timeout? When entering the program, please disconnect the signal line with hx711, otherwise the program display cannot be connected. Please input the program and then connect the signal line. If the wiring is loose due to moving the board when the board is powered on, the screen display may be garbled. At this time, please disconnect the power supply and plug it in again to restore the display.
