Comments on: Arduino – Control 2 DC Motors Via Bluetooth (Perfect To Build a Robot)

I have followed this tutorial: https://randomnerdtutorials.com/arduino-control-2-dc-motors-via-bluetooth/ and made no changes at all to the instructions. However, when I use the app, everytime I press forward, it will keep going forward forever and will not STOP even when I press STOP and then after this a broken pipe error will occur? Is there a way to remedy this or how can I alter the code so that the forward button only drives motors forward for a couple of seconds?
Help would be much appreciated.

Having trouble with this at the moment. Anyone trying in project in 2023/2024?
I have a Bluetooth connection but the motors aren’t running when I press on a command and I’m getting the message “Broken Pipe.”
Any tips for this issue?
I’m pretty sure I wired everything right, unless there’s some certain things you gotta do when uploading the code on IDE.

Hi! i am interested in your project! May I know which schematic diagram you are using? I am currently using tinkercad, however, there are limited components in there.

Do we have any specifications regarding the ic driver position

I tried this project.I powered Arduino with power bank and Dc motors with 4AA batteries.I used L298N motor driver module.But dc motors not running.I check dc motors with direct current and its working.Bluetooth Module and Motor Driver is also working.Can you help me with this?

In reply to m-almajed. HEY please can you tell me did you use the same code for Dual H-bridge? L298N

Hi,
thanks for your feedback.
That question requires almost an entire tutorial.
What I can tell you right now is that it works like it does with the Arduino… The bluetooth module will establish a communication via the TX and RX pins.
and your smartphone will establish a communication with the bluetooth module.

It will also depend in which PIC you’ll be using. you need to read the datasheet…

I know this is a very old post already, but let me chip in on the voltage divider issue. I have been using hc05 modules since I think 2011 on an arduino. To be exact I used 4, that eventually all went dead. So on average they lasted about 2 years, but that’s still relatively short. Had them connected without any voltage divider on the Rx pin coz that ‘should be OK’. Nevertheless, i never had such a high turnover rate on electronic components as with the hc05, except maybe for sd cards in a raspberry pi.
Have ordered a new hc05 but this time i will be using a voltage divider.
I guess that the 5volt level perhaps somehow slowly deteriorates the rx pin of the hc05

Hi.
We don’t have a guide for that motor driver with the Arduino.
But we have a guide with the L298 motor driver with the ESP32.
The wiring is similar.
Here is the article: https://randomnerdtutorials.com/esp32-dc-motor-l298n-motor-driver-control-speed-direction/
I hope this helps.
Regards,
Sara

Hey very good project bro, but can you send the connection with L298 motor driver.
thanks
