Issues with mBlock Programming for Smart Car

#1

Hello Makeblock Community,

My name is Emmanuel Katto. I’m currently working on a project using the Makeblock Smart Car and programming it with mBlock. However, I’ve encountered some challenges that I hope you could help me with:

Sensor Integration: I have integrated the ultrasonic sensor with my Smart Car, but I'm having trouble getting it to respond correctly. I’ve tried several code snippets available in the community, but the car doesn’t seem to react appropriately. Are there any reliable examples or tutorials that specifically cover using the ultrasonic sensor with the Smart Car?

Remote Control Functionality: I would like to implement remote control functionality using my smartphone. I’ve seen references to using the mBlock app for this purpose, but I'm unsure how to set it up. Any tips on pairing my Smart Car with the app?

Troubleshooting Tips: If the car isn't moving or responding to commands, what are some common troubleshooting steps I should take to diagnose the issue?

I appreciate any guidance or resources you can share! Thank you for your support!

Best,
Emmanuel Katto

  • Can you share some examples of your code?
  • What board are you using as a base (mCore, mBot 2, etc.)?
  • Troubleshooting steps depend on the code and device you are using.

Hi Emmanuel,

It sounds like you’re working on an exciting project! Here are some resources and tips that might help you with your Makeblock Smart Car:

Sensor Integration

For integrating the ultrasonic sensor, you can check out these tutorials:

  1. Explore mBot Tutorial #5: The Ultrasonic Sensor - This video walks you through programming the ultrasonic sensor using mBlock⁵.
  2. Makeblock Ultimate 2.0 - Tutorial 6 - Ultrasonic Sensor - Another helpful video that covers the basics of using the ultrasonic sensor⁶.
  3. Programming Makeblock Starter Robot - Ultrasonic Sensor - This tutorial explains how to measure distance and perform actions based on sensor readings⁷.

Remote Control Functionality

To set up remote control functionality using your smartphone:

  1. Download and install the mBlock app from your app store.
  2. Connect your Smart Car to the app:
    • Enable Bluetooth on your smartphone.
    • Power on your Smart Car.
    • Open the mBlock app, tap the Bluetooth icon, and follow the prompts to connect².
  3. Program the remote control:
    • Use the mBlock app to create a custom remote control interface.
    • Design the controller by adding icons and programming commands for each icon¹.

Troubleshooting Tips

If your Smart Car isn’t moving or responding to commands, try these steps:

  1. Check the power supply: Ensure the batteries are fully charged or replace them if necessary¹².
  2. Verify connections: Make sure all cables and connections are secure and correctly plugged in¹³.
  3. Update firmware: Sometimes, updating the firmware can resolve issues. Connect your Smart Car to mBlock and check for firmware updates¹².
  4. Test individual components: If a specific sensor or motor isn’t working, test it separately to identify if it’s a hardware issue¹³.

I hope these tips help you get your project back on track! Feel free to reach out if you have any more questions.

Best of luck with your project!
