Q1. How many sensors we can use in one Arduino UNO at the same time?
Q1. How many sensors we can use in one Arduino UNO at the same time?
The memory of Arduino UNO is very small. It is difficult to use more than two sensors at the same time.
Q2. There are no Gaduino blocks in the mBlock extension.
Q2. There are no Gaduino blocks in the mBlock extension.
Make sure you have added the Arduino UNO in "Devices".
Q3. I've already added an extension block, but new blocks doesn't appear.
Q3. I've already added an extension block, but new blocks doesn't appear.
This appears to be an error in the mBlock itself. Try refreshing your browser and coding again (don't use saved code when doing this).
Q4. I cannot see any data in the IoT Platform
Q4. I cannot see any data in the IoT Platform
Check if the green (or blue) LED on the back of the LTE Module is blinking quickly. If the LED is off or blinking slowly, it means that it has failed to connect to the network operator.
Make sure there are no spaces before or after the server or port in the block you're typing in.
Make sure you've entered the token correctly.
Q5. I get a "compile timeout" error when uploading.
Q5. I get a "compile timeout" error when uploading.
The Web version compiles on the server, and the PC version compiles on the user's computer.
When using the Web version
This is a limitation of the mBlock server. Remove heavy extension blocks (e.g. OLED blocks) or use the PC version.
When using the PC version
Please turn off all unnecessary programs except mBlock.
Use a computer with better specifications.
Q6. I don't know which COM port to select when uploading. (Windows)
Q6. I don't know which COM port to select when uploading. (Windows)
Right-click the window icon on the taskbar and open [Device Manager].
Under Ports (COM & LPT), you can see the port number written next to "USB-SERIAL CH340" or "Arduino Uno."
Q7. After removing the extension block, I get a "TypeError."
Q7. After removing the extension block, I get a "TypeError."
Save the file you are currently coding in and restart mBlock.
Q8. I don't see anything on the serial monitor (e.g. Herculus)
Q8. I don't see anything on the serial monitor (e.g. Herculus)
Make sure you've added the "write hello to serial port" block to the beginning of your mBlock code.
