Arduino Obstacle Avoding

Other Hardware Motors, Mechanics, Power and CNC

I am using the Arduino Uno R3, L293D Driver board shield, HC-05 Bluetooth module, HC-SR04 Ultra-sensor, LED, and a 7.4V battery to build a Arduino Avoiding Obstacle Car.

I have connect all components to the Driver shield board and uploaded my code to the board but plug out the TX and RX of the Bluetooth module before I upload the codes but the manual functions do not work. I only have manage to get the autonomous code to work and I have no idea why the manual commands are not working on any app I used for the Arduino. Can you please help me?

Please read and follow the instructions here for posting code and wiring diagrams.https://forum.arduino.cc/t/how-to-get-the-best-out-of-this-forum/679966

Okay. How about this. List some apps to use to control the Arduino Avoiding Obstacle Car manually.

Schematics is the way to tell. Your verbal description is worse than too little.
Be glad there was no smoke.

Assembling all those devices should be done one device at the time, verifying it works. Did You do it that way?

They are not apps, they are sketches.

You said it.

Try this topic, but modify it for your use...

The codes and components work. The problem is the HC 05 which is the Bluetooth module. I have listed all the components used for this project. I do not know what else to say plus I have stated that I ran tests on each components and they all work. The problem is not the components or codes. It’s just the Bluetooth module. It is my first time using this. I even created an autonomous code and it is moving perfectly fine but when I tried to control the robot car manually it is not working. I believe I need to configure the Bluetooth module as a slave mode

What else to say You write...
You use words. Engineers use more.
All circuits have been tested working. That's really good. Still, running it all together calls for schematics.
The next request is, please post the code.
Take it or leave it.

See post #2.

Thank you!

The request was for you to submit a wiring diagram. Drawings help show the meaning of the text. "A picture is worth a thousand words," that we all hear, says how complex ideas can be described more effectively with one picture than long explanations. Theory of Operation describes how the project works, but will not cover every device, pin, wire and voltage level.

If a picture is truly worth a thousand words. Why not state something like; Can you please add a picture or any diagrams to help me better understand the issue with your circuit? For example, something like this shown in the link below on what another person has provided.

Because, you already know it to be true, yet withheld it. Why must the information be dragged from you? Why not supply it without prompting? Do you see how this should work?

And this...

Which refers to this...

But you ignored it and did your own thing. What's next?
