Hi do any body know if there is a place where i can get help with my sketch online
I have bought an arduino and 2 3A motorshields. 2 motors will be connected to each shield
I can do a little programming but not much, can i get 4 PWM signals from one joystick
I have build an ROV where my motors are controled by relays, and now i would like to make it analog
i am thinking about having 1 arduino at the top and one in the ROV
so one will have the joystick and the other one the motorshielde
is that possible,
can do a little programming but not much, can i get 4 PWM signals from one joystick
Not exactly... Not directly.... You can get X-Y information from the joystick and your program can generate the PWM.
A joystick either gives you two variables, or sometimes it's just a 4-postion switch with 4 "states" (plus center-off).
Maybe you can make a table or a chart to see if you have enough information to control 4 motors the way you want.
Input -> Software -> Output. The joystick is your input, and PWM is your output.
Do you have an analog joystick, and can you read the joystick?
Can you control the motors with PWM?
You'll have to figure-out what kind of data you're getting from the joystick and how that data relates to motor movement. If you can figure-out the logic (and if what you're trying to do is logical) the programming should be possible.
Once you can read the joy stick and move the motors with PWM, you'll need to figure-out the logic of what your sketch needs to do.
I'd suggest starting-out by controlling just one motor.
If you have any trouble with any of the above, post your code and you can get some help.
After you get one motor working, you should be able to add 3 more.
Hi
Thanks for the reply, i will start and see if i can get one motor to work
with a sketch from in here, and then maybe get all 4 motors added later
