Arduino R3 ,L293D and Brushless motor (Include EsC)

[yon88]

Hello Seniors
I am still a beginner to these coding and Arduino things.
I have made my own little study for my project.
The component I use in my project:

ESC 50A

Electric Duct Fan/ Brushless motor
https://shopee.com.my/70mm-duct-fan-3000kv-Motor-Spindle-4mm-64mm-fan-4500kv-motor-90mm-duct-fan-1750KV-motor-for-jet-RC-EDF-For-RC-Airplane-i.53025383.2423629326?sp_atk=82b0cdf2-96de-4e9c-ad82-68800456f95d&xptdk=82b0cdf2-96de-4e9c-ad82-68800456f95d

Bluetooth HC05

Arduino R3

My goal here to run the motor without speed controller or potentiometer.
Just use the app ( On/Off) for the motor.
Regarding the app is okay as long its receive the right command.
The problem is the ESC and Motor
I don't know what is the right coding for this.
But if there any add in component required to move the EDF
you may suggest
Your response kindly appreciated

Welcome to the forum

@yon88

The problem is the ESC and Motor
I don't know what is the right coding for this.

You can control the ESC using the Servo library

[yon88]

okay....I tried this before
Could Senior help provide the code here so I can test it
It might be a different library though

[UKHeliBob]

Connect the ESC to the Arduino as if it were a servo, ie 5V, GND and a data pin of your choice

Load the Servo Sweep example and change the data pin used if you have chosen a different one and upload the sketch

If you have provided external power to the motor properly via the ESC then the motor should run from zero to full speed and back then repeat

How is the motor powered ?

I apologize. To be honest I am kinda desperate. Thanks for your response. I will try this and update you later

There is full sketch through the link

I know the skecth looks funny but they're all I have
My goal is to build an Bluetooth RC car with EDF on it.

EDF (connected to ESC 50A ) is powered by 4s LIPO
Also . I intended to use L293D to control the EDF while the four DC motors are connected to it
Right now, I am just able to move the model in the x and y directions except for EDF.
It just could not run.

[yon88]

yes The Arduino R3 is combine with l293D
If there are changes component, pleases suggest so I can make improvement

[UKHeliBob]

Forget about the project as a whole for now and concentrate on getting the BLDC motor working alone

@yon88

I intended to use L293D to control the EDF

Can you use an L293D motor driver to control a BLDC motor ?

[yon88]

If you mean through ESC , Then I not sure because I still testing the BLDC using Arduino alone. That's resulted the BLDC didn't run ( ECS powered by 4S lipo battery and Arduino powered by adapter) . I want to check the BLDC is in good condition or not before I connect it to L293D. I don't even know if the coding correct or not. I here need Seniors's coding to run it. I also already install the
Servo.h library but still not able to run the BLDC.

My target here is to run the BLDC first through Arduino before moving to next phase where we going to use L293D.

For L293D
I not even sure if that works. If we refer to the circuit , I connect the ECS's GNd , Pwn and 5V to Serv1 on L293D.

[UKHeliBob]

Have you tried the Sweep example as I previously suggested ?

Please post a schematic of how your ESC, BLDC motor and Arduino are powered and connected. A photo of a hand drawn circuit is good enough

[yon88]

I apologize for late reply because i was away from my project for a while
Senior, this is my whole connection.
