Good afternoon all!
I am currently working on a trike project using 2 brushless hub motors salvaged from an old kids hoverboard, and 1 generic Chinese controller for each motor.
I am trying to control both motors with one throttle, but just splitting the signal wire to go to each controller is causing problems.
My question.. I have an arduino uno r3 and motor shield laying around from an old project (wind simulator for sim racing), is there a way I can use this to receive the input signal from the throttle, and repeat it out to each controller separately, rather than trying to just split the one wire.
I am very compitent with dc electrics and the mechanical side of things as that's what I do for a living, but I am a complete novice in the arduino area so all help would be greatly appreciated!
What input signals for the motor shield should you provide?
The three connections are +5V (Red lead) , 0V (Black ground lead) and signal out (White lead) .
Twisting the throttle simply varies the strength and polarity of the magnetic field adjacent to the sensor, which sends a corresponding voltage of between 0.8V and 4.5V to be sent to the controller.
Its only the signal I need to repeat.
I mean not the throttle sensor but motor driver.
My apologies, I don't know what you mean!
As I said I'm totally new to ardunos so I'm afraid you may have to explain things as if I was a child!
You did connect the gnd of the controller to both gnds of the motor controller?
You have what is called a Hall Effect Throttle controller.
Can you please post some images of the hardware that you have?
Explain please what is generic Chinese controller? What is its input signals?
Give please your wiring diagram as advised in post #6.
I have limited pictures on me as I'm nowhere near home atm, I will try to take some better pictures when I get home.
I have attached pictures of the controllers being used, and the throttle.
No I didn't connect the ground from the throttle to both controllers, only the signal wire, the earth and live from the throttle are connected to one controller only. I did this because it was something I read online, saying only the signal needs to be split. I'm guessing this isn't right?
I will also make up a wiring diagram when I get home.
Everything else is wired right, both controllers/motors work as they should individually with the throttle only connected to one at a time.
Take a piece of paper and carefully draw a diagram of your connections.
