Hello all,
Let's just start by saying that I'm very new to the Arduino scene(and this website), but I'm working on a project for a class in mechanical engineering and need some minor guidance. (They don't very much teach the electric side of the engineering world to us mechE's)
The end goal is to control 4 DC motors, independently, through Arduino code.
To start, I just want to set up a single motor to get it going. I have Exceed 18A ESC( http://www.hobbypartz.com/07e-flyfun-18a.html )and Exceed brushless motor( http://www.hobbypartz.com/86ma54-2205-4500kv.html ) all being powered currently by a 11.1V 4000mA 20C battery (want to change this out for a power supply, but just using the battery for testing. Not what psu to buy as 4 motors would draw near 20 amps running at 9000 rpm that is desired for the project).
I've been referencing the following guides:
(1) https://forum.sparkfun.com/viewtopic.php?f=32&t=32036
(2) http://techvalleyprojects.blogspot.com/ ... orial.html
for starting to arm a single ESC, but it doesn't seem to be working correctly. Upon running the code from guide 2, the motor would continue to beep repeatedly non-stop while the motor jittered back and forth in very minor like 1 degree increments. I believe after reading the ESC manual that this pattern was that the battery voltage is either too low or too high. This would make no sense to me as the ESC is rated for 5.6 to 16.8V.
Any help is appreciated on either the PSU question or arming the esc and getting the motors spinning.
Thanks
