Hi everyone,
I am designing my own drone and I need some help regarding that,
I want to drive four 12v centre shaft gear type motor,for that I used 2 L293D driver modules(for cw and ccw direction) and I connected it with arduino uno
now ,I don't know how to establish connection between arduino uno and APM 2.8 and
is it possible to control the dc motors using RC transmitter for rotation in cw and ccw directions? and
suggest me a source of power supply to run the 4X 12v dc motor
How big is this drone to be?
-jim lee
75cm across diagonal
the 12v dc motor is for some other application
for propellers I'm gonna use brushless dc motor so please don't confuse it
You could just gear down four more brushless motors and run them off RC car controls. They have both reverse and forward. You could be up and running in minutes. With power to burn.

can bldc be programmed to rotate in both directions?
vicky_luffy:

Why would you want the 'program' to be able to reverse the rotation direction of the brushless motor on a quadcopter\drone ?
Do you have any previous experience of radio control models, brushless motors, ESCs and the like ?
If you're talking about 2 completely different projects I suggest you start a new thread for one of them and edit this one to make it clear which you're talking about here.
So far we have 12V DC geared motors, unspecified brushless DC motors, L298N drivers (that definitely don't work with brushless motors), APM 2.8 but no mention of the ESCs that the brushless motors will need.
And a 75cm drone is a really big heavy one for someone with apparently no experience and little knowledge of drones.

thank you so much for your response
my project is to vary the size of the arms of the drone
for that purpose I use 12v dc motor(4 numbers)
then I have to measure the entire weight of the drone and then I have to go for the bldc motor
srnet & slipstick, just stop!
luffy, what is it you are calling a bldc?

Stop what ?
Stop admonishing the person before you read what they are saying.

or assuming they have no clue as to what they are doing.

Just, be cool, see the lay of the land first.

I did not, the posts you have quoted were not mine.
I asked very reasonable questions;

Do you have any previous experience of radio control models, brushless motors, ESCs and the like ?
I get frustrated with people drip feeding little bits of information. So I'm happy to leave this one alone. Bye bye.

...for that I used 2 L293D driver modules...
Meaning OP still has a lot learn before venturing into a drone project.
The L293D is for tiny toy motors.

hello everyone,
I just need all of your help and all your replies were meaningful and helpful if you have knowledge about please share in this thread
we will walk through this project together
objective of my project is to resize the size of the drone by varying the size of the arm
please don't bother about the mechanism of varying the size,I'm already done with that
now the question is
1)how to interface arduino uno and APM 2.8(ardupilot flight contol board)?
2)what battery source can I use to power four 12v dc motor?
jimlee,bldc means brushless dc motor
Thanks a lot everyone

What battery are you planing on using for the flight motors? Volts & size? I'd use that for your arm motors.
Also, if you can just use the RC car controls for your arms, you would probably be lightyears ahead. Designing something like that from scratch is going to be an entire black art learning curve. RC stuff is cheap. You will be able to control the drone & the arms with the same basic code.
Now, why do you want to interface the flight controller to the arduino?
And, have you ever flown one of drones yourself?
