DRIVER INSTALLATION
Normally, the driver for this board is automatically supported by the Arduino IDE. However, in some cases, the Arduino IDE may not recognize the board properly. If that happens, please follow the instructions below to install the driver manually.
TO BE UPDATED
ARDUINO IDE BOARD SELECTION
- Connect the DIYables STEM V3 board to your computer using a USB cable.
- Launch the Arduino IDE on your computer.
- Select the Arduino Uno and COM port.
TROUBLESHOOTING
When you upload your sketch, you may see an error like:
This means another program is already using that COM port. Most often, it’s because the Arduino IDE’s Serial Monitor is open. To fix this:
- Close the Serial Monitor.
- Disconnect USB cable from PC, then reconnect again.
- Upload your code again.
- Once the upload succeeds, reopen the Serial Monitor if you need it.
