I want to upload the sample program to the Arduino board, and then the motor does not work
after turning on the power. What is the reason?
A
：
Firstly, check if the green indicator on the Arduino UNO board is on. If it is not on, it means the
power supply is not normal. Check whether the battery voltage is above 6v. Then check whether the motor's
wiring port is consistent with the port set in the program. Turn it on again.

When the motor is running, the power consumption is large. You need to ensure that the battery
has sufficient power. You can try to charge the battery before turning it on.
Software Installation
Install IDE software
Unzip the Arduino software installation package (path: MotorDriverBoard\ArduinoIDE) under the
MotorDriverBoard folder, or download it from the Arduino website, download the address :
https://www.arduino.cc/en/Main/OldSoftwareReleases#previous
Figure 4-1 Arduino IDESoftware installation package
Unzip the zip file and double-click the arduino.exe installation file to install it. Because the installation
of “arduino.exe” is very simple, it will not be explained here. It is recommended to quit the anti-virus
software during the installation process, otherwise it may affect the IDE installation. After the installation is
complete, click "arduino.exe" again to enter the IDE programming interface.
